Add tests for semantic and add syntax for it to ebnf
...
Syntax is ?[ ...]?
For example:
[EBNF num=. ?[ number? ]? list=list:x num:y => [[ drop x y + ]] | num EBNF] { 1 2 3 4 5 6 } swap call .

This creates issues when recompiling a an existing EBNF parser for reasons I've not yet tracked down. Disabling it slows things down but makes things work correctly till I investigate the issue.
