    dedentTokenName: TerminalName

    The name of the token used to denote deindentation in the grammar. A possible definition in the grammar could look like this:

    terminal DEDENT: ':synthetic-dedent:';

    'DEDENT'
    ignoreIndentationDelimiters: IndentationAwareDelimiter<
        TerminalName
        | KeywordName,
    >[]

    The delimiter tokens inside of which indentation should be ignored and treated as normal whitespace. For example, Python doesn't treat any whitespace between ( and ) as significant.

    Can be either terminal tokens or keyword tokens.

    []
