Returns the next token, with a special case for EOF after a bare $ in a GString.
After GStringBegin or GStringPart matches a trailing $ at the
end of input, Antlr marks _hitEOF and would skip
GSTRING_TYPE_SELECTOR_MODE entirely on the subsequent call. Detect that
situation and report the dollar-body error instead of a generic unexpected-EOF parse
failure.
Report a lexical error. When the failure is inside
GSTRING_TYPE_SELECTOR_MODE (after a $ in a GString), emit the
dedicated dollar-body diagnostic instead of Antlr's generic token-recognition message.
e - the recognition failure raised by the ATN simulator Abort lexing on the first lexical error. For an invalid character after $
in a GString, throw GroovySyntaxError so the parser layer can surface a
source-located syntax error without retrying SLL?LL or falling back to a generic
exception message.
