That's messy when you are using /c. What if you wanted the counts
of everything that wasn't a digit for error reporting?
@freq{ ... what ... } = tr/0-9//c;
You can count them now, but with this new proposal, you'd not know
which you are counting.

It's not returning a hash. I like the proposal that has it return a
paired list, similar to the semi-paired list we get with a capturing
split, or a list-context m/()()/g match.
