Yes, that's the sort of thing I mean. I actually want it for enum defs:
my Scalar enum hex « :zero(0) one two three four five six seven eight nine
:ten<a> eleven twelve thirteen fourteen fifteen »;

You can replace the whole darn grammar if you like, so it's certainly
possible. I don't think we'll go out of our way to make it easy
though. Probably requires a lookahead on the identifier rule to
see if the next thing happens to be a => workalike. Alternately,
you have to do syntax tree munging with an infix macro, since by the
time you see an infix macro its left argument is already parsed.
