> Currently original script text is not available for validation errors, which makes it
difficult to generate helpful validation errors (besides reporting the error and the beginning
line/column where the error is located). It would be helpful during validation error reporting
to pass the tokenized text which is already generated by antlr to classes such as statements
and expressions so that the script text can be utilized to generate more helpful error messages,
which can include information such as the statement that generated the error.
