To try and make it easier to pick (ASCII) operators, a simple table of
what's given away and what's available. Please let me know if there are
any mistakes.
If anyone knows how to fill in the "???" parts, be my guest!
\W+ Term (pre|circ) Operator (post|in)

~~ AVAILABLE? smart match

Y zip()
many still available!
With double characters (like ~~), "AVAILABLE?" means that if we start
using that, stacking of the single thing will start requiring
whitespace, as with = and == in $foo = =$fh)
"ws?" means that whitespace may be needed for disambiguation.
I left out colon and semicolon because they're too special to fit in a
term|op table. I think it's more than safe to assume they're taken :)
<> is more flexible than {}, [] and () because it's a quoting operator
(the inside is not an expression).
I think it's best to ignore entirely the fact that we can use more
triple character proper operators :)
