Harvey-

Tis true that guile's handling of hash tables is not the best,
especially in the resize / mapping department. Some people on this
list recommend using slib's hash tables, but I generally use what
is available natively in guile:

hashq-ref
hashq-set!
hashv-ref
hashv-set!
hash-ref!
hash-set!

When I need to iterate over the hash table, I just use a do loop.

I would love to have a module that implements your suggestions,
though. A user could bring in the module, and it would transparently
redefine the above functions, but it would also provide mapping
functions and automatic resize.

The next time I need to iterate over a hash table, I won't write the
requisite do loop, and instead I'll write this module.
