(I'm going to RFC these if nobody presents any killer complaints about
them, it's just that writing RFCs is more work than I want to go through
for tiny little changes like these, especially if they turn out to be
dumb).
%hash in scalar context should return what scalar(keys(%hash))
currently does.
Resetting an each() should be done in some other way than calling
keys() or values(). Perhaps reset(%hash)? I'm subfond of the current
reset() semantics (symbol table crackheadery + single-match regexp
resetting).
I was against the idea of hash context, but I'd love it if:
foreach ($k,$v) (%hash) {
...
}
and
foreach ($k,$v) (sort %hash) {
...
}
magically "worked". Traversing hashes is so common, it'd be nice to
find a way around the keys() circumlocution. The former is already
suggested, and I like it. The latter requires the parser to
understand sort being passed a hash.

justify)
