Sounds good. Unless there are other suggestions, can someone make the
minor changes and commit it to contrib?

fmap is not recursive. When given a list, it would only act at the
top lev
Hi,
Isn't tree-reduce similar to clojure.contrib.generic.functor/fmap (though
fmap preserves the type of the structure, while your function returns seqs
of seqs ...) ?
(Ah, and I find that the name reduce here is a bit misleading, since the
operation really does a mapping from a tree to another ?
I've uploaded tree-utils.clj to the files section.
http://groups.google.com/group/clojure/web/tree-utils.clj Here are
some example usages:
Subtracting two (or more) trees element-by-element:
user=> atree
[[1 2] [3 4 5] [6 7]]
user=> btree
[[2 3] [4 5 6] [7 8]]
user=> (tree-reduce - atree btree)
