This is basically the issue. I've never used a Data.Map in any "real" code
(that was written by me... Data.Map is used in xmonad, upon which I hack,
but don't feel motivated to propose alternative requirements for
installation), only in toy codes. And for that purpose, I didn't really
want to go to the trouble of seeking out and researching various
For a trivial "count the frequency of characters in a text file" toy code,
it hardly seems like a reasonable expectation that a beautiful
implementation should require the installation of extra libraries.

cabal-install may help, but what I'd really want is packaging in debian.
That's my (biased, because I used debian) standard of a "maintained, useful
library." It's obviously a biased standard, but it isn't too hard for a
package to get into debian, and if it *does* get into debian, it suggests
someone cares about it. I don't like requiring obscure packages that
perhaps have no code review, and perhaps have no users other than the
