Encode optional / Maybe types #230

Closed dmjio closed 3 years ago

Was perusing the google group and noticed there is no support for encoding Maybe types in an AST. This would really be a nice to have for a grammar I'm modeling. Has there been any progress since this these issues were posted?

No progress I'd know of so far. That would be nice to have. If you want to give it a try... (Such a feature is a bit of work since it needs to be supported by all backends.)
