Ah excellent!

I could contribute fash-keys, fash-values, fash-map, and fash-for-each.
Those shouldn't be too difficult to do.

As for deleting elements, why don't we take the simple way for now?
Let's make a procedure that just uses fash-fold and copies over to a new
fash, sans the removed element.  We can note that it's O(n) but that a
faster version is possible but needs to be writtten.

What do you think?
