Not sure why you would need :: and ;; for that. Bernd Paysan and I
have discussed factoring [: and ;] into a part that does the nesting
("[{" and "}]" <2015Jul29.093553@mips.complang.tuwien.ac.at>), and a
part that does the rest (which is mostly :NONAME and ;).

The parser generator Gray uses {{...}} for actions.
