Ok, thanks a lot. I did some more reformatting so that the layout is
more in line with the rest of the library, and fixed a couple of minor
bugs and typos. I also removed the do/map stuff in dict.q (while this
might be useful, I'd prefer the new version to be a drop-in replacement
for the old one for now). It is in cvs now.

There's still a minor issue with the inserta/deletea operations,
however. The problem is that you used syntactic equality (foo X X = ...)
rather than (=) to decide equality of two key values. That will be ok in
most cases (hdict should be fine as the real key there is always an
integer), but for dict/bag/set you don't know what the actual key type
is, it may be *any* ordered type, and some key types might well use a
version of (=) which goes beyond simple syntactic equality, see
"Non-Linear Equations" in the manual
[http://q-lang.sourceforge.net/qdoc/qdoc_7.html#SEC42] for an explanation.

I'll try to fix this (shouldn't be too difficult) and give it a first
test drive with a couple of my programs. If that works ok I'll upload a
new release candidate later today.

Cheers,
Albert
