Actually, you could make _ less special by still binding the value to

Combining the two would feel a bit weird, but should still be possible.
I thought _ was also commonly used as:
first, -, last = (1, 2, 3)
as a generic don't care about assignment. I guess since the above will create a local, so not overwrite a 'global' function _ for translations, so the above usage works as long as that function (or whatever namespace you are in) doesn't use _ for translations. As long as the bindings in match also make the symbol a local (which seems reasonable) then you would get a similar restriction.
