Cannot add @position to external rules about peginator HOT 2 CLOSED

Without @position, UnicodeSpace will be a type alias to String. I guess in your example it would become a struct with a single value and position fields? Or just the position?
I'm not sure how universal these would be and if it fit anyone else's use-case. I'd prefer to wait for someone else with a similar problem.

For now I'd suggest doing something like:

@extern(crate::utils::unicode_whitespace)
UnicodeSpaceExt;

@position
UnicodeSpace = spaces:UnicodeSpaceExt;

Good idea
