Normally I would agree, but in this case I think the new macros you
proposing would become obsolete once we have the better hash table
creation functions I have in mind. And if we're going to update all
places where we create hash tables, I'd rather update them to something
really nice than a small improvement.
I couldn't let it go (nerd-sniped). So here's a patchset that adds some
macros that I think are pretty nice. Including a foreach_hash macro.
I'm a bit on the fence about the C11 _Generic code to determine whether
we should use HASH_BLOBS or HASH_STRINGS based on the type of the key.
It works really nicely in practice, but I'm worried it's a bit too much
magic. Probably we should at least have an override to allow using
HASH_BLOBS anyway for a char array (in case it's not null terminated).
