2023-01-22 Update copyright
2023-01-28 Add 'TolExpression'. Change 'AssignmentStatement', 'ConditionalExpression', 'DoStatement', 'Expression', 'IfBlockStatement', 'IfStatement', 'SelectStatement', 'WhileStatement'. Add support for 'Var s = Sub ...'.
2023-01-28 Add support for 'Exit Constructor'
2023-01-29 'IsNamedArgument': Add a rough heuristic to warn about possible syntax error with '=' and ':='

---

2023-02-01 'CallStatement', 'ConstructorStatement': Add tests for errors 'CALL CONSTRUCTOR is available only in a CONSTRUCTOR' and 'CONSTRUCTOR VAR cannot have a parameter list'
2023-02-07 'ExitStatement': Add test for error 'CALL BASE is available only in a CONSTRUCTOR'
2023-02-13 Remove 'Int', 'Real', and 'UInt' as primitive data types
2023-02-17 Change conditional compilation from directives (@If...@Else...@End) to statements (Const If...Else...End If)
2023-02-21 Tokens 'string_literal' and 'malformed_string_literal': Remove commented out parts
2023-02-27 Add command line switch '-t' to display time elapsed
2023-02-27 Change invocations of macro 'ID()' to use constants 'STMT' and 'EXPR'. These values are switched with each other.

---

2023-03-03 'NamedString': Change names of some time constants (eg, $TIME_24_SEC becomes $TIME_24HMS). Fix case-sensitivity bug.
2023-03-07 'StringExpression': Remove vector v and use wstring res directly. Conditionally print res if arg '-v2' or greater.
2023-03-09 'Deprecated': Divide '@' and 'Deprecated' into two tokens. Add 'OptionalNewline'.
2023-03-09 'EnumMember', 'EnumStatement': Permit many constants on the same line with semicolons. Add 'SyncSeparator'.
2023-03-17 'Argument', 'ConcatenationExpression': Remove unnecessary tests for ampersand errors which are no longer possible
2023-03-26 'option': Add 'Mod_floored'. Change 'When_id_Begin_id' to 'When_Begin_id'.

---

2023-04-01 Add union 'Modif::arg' AKA 'ModifArg'. Update copyright.
2023-04-01 Add arguments for modifier `@SI`: BINARY, LARGE, and SMALL
2023-04-02 'EnumStatement', 'SelectStatement': Add new modifier `@Strict` to make sure enumeration constants obey special rules
2023-04-10 Change 'fixed_literal' to a prefix of 1 or 2 characters. Remove 'malformed_fixed_literal'. Change 'PrimaryExpression' to handle numerics with the new 'NumericExpression'. Fixed literals can be prefixed or suffixed with `@`.
2023-04-18 Change 'DivFunction' to 'DivisionFunction'. Add new functions 'Mod' and 'Rem' that return the first arg if the second is zero.
2023-04-20 Identifiers can use the characters micro and mu. Add pragma 'bad_identifier' to find incorrectly encoded files, missing the BOM preamble. This problem causes the scanner to assume ANSI encoding.
2023-04-25 Add new function 'HasWhitespace'. Use it in 'AssignmentOperator' and 'NumericExpression'.
2023-04-26 'GotoStatement': Change 'Expression' to 'TolExpression'

---

2023-05-03 'SyncNewline': Move 'Get()' to before 'Err()'
2023-05-14 'NumericExpression': Combine duplicate strings; Do test for invalid chars in fixed literal; Make sure error always refers to the first char
2023-05-20 Move enum 'mods' and array 'm_name' into macro 'NAME_STRING_PAIRS'. This makes sure that the two do not become out-of-sync.
2023-05-21 'Modifier': Prevent whitespace after at-sign. 'NumericExpression': Prevent fixed literal with two at-signs.
2023-05-21 Make as many strings into Unicode as possible
2023-05-23 Refactor 'NumericExpression' to remove 'UnitExpression' and add recursion
2023-05-26 Change class 'param_type' to 'param_validator'. Change method 'modifier' to 'add'. Add method 'none'. Make sure Property's Set procedure has one parameter.
2023-05-26 'PropertyStatement': Cannot use GET with `@WriteOnly`, SET with `@Iterator` or `@ReadOnly`, `@Iterator` with `@WriteOnly`
2023-05-26 Fix incorrectly lexing of `@modif1@modif2` as 'typed_identifier'
2023-05-28 'PropertyStatement': Cannot use GET with `@WriteOnly`, SET with `@Iterator` or `@ReadOnly`, `@Iterator` with `@WriteOnly`
2023-05-28 'Module': Make 'Program' and 'Library' clauses optional, where 'Program' is the default

---

2023-06-04 After upgrade to VS2022, comment out line that caused a new error
2023-06-21 Add 'EventName', 'SimpleNonCallExpression'. Change 'QualifiedName' to return a string. Change several uses of 'QualifiedName' to 'EventName', 'SimpleExpression', or 'SimpleNonCallExpression'.
2023-06-21 'CallStatement': Hack lets it use 'UnenclosedArgumentList' again (eg `Call test 123`)
2023-06-24 'CallStatement': Make the hack better. Add test for right bracket.
2023-06-27 'StringValue': Throw exception (`out_of_range`) for bad char codes

---

2023-07-29 Replace token `date_literal` with subtokens parsed by `DateTimeExpression()`. Add `IsDateTime()`. Calls to these functions move from `PrimaryExpression()` to `NumericExpression()`.

---

2023-08-08 Add several calls to `ResetPeek()` when a function calls `Peek()` more than one time
