What meanings do we want to convey?
Regexp are now more like functions, their field of use
has enlarged to the parsing of whole language defined by grammars. And parsing grammar
the selling point. What can do more can certainly do less.
I would call them grammex
en to get the
point thru: "you can parse using grammexen, you can't using
plain old regexen". It makes clear that perl6 is not only
for assembling or lexing strings but that it can handle
complex languages. grammex ends like regex, so it is a reminder
that it is a related concept.
I want to spell it loud and clear. I don't want to hide the
clue about grammar in an acronym because most acronyms are
