That was our original thought (well, the first thought after .{''}),
but the problem that worried me was that if the user mistypes it as
.{*} instead of .{'*'}, it parses and silently does the wrong thing.
So the key wants to be something that doesn't parse as a term like *
(or worse, give a probabalistically delayed parse error like /).
We looked at most of the keys on the keyboard... :)
In the end, I picked .<?> because it looks fairly distinctive in normal
code, and kinda asks, "Well, what is it really?" But it's not writ in
stone yet.
