Isn't that count fairly recent (like within the past year or so)? I recall
it being one of the things that came in with "new Hackage".

I remember Louis as being quite active on the Libraries mailing list
as the queue package was developed and possibly was even keen to have
a priority queue include in the Base library "Containers". So I expect
the code is of pretty high quality and a quick scan indicates Louis
went as far as adding SPECIALIZE and INLINE pragmas for performance.
However, queues seem to be relatively unused but functional
programmers (Chris Okasaki's famous Edison data structures have a
similar "small" download count on Hackage). Maybe even the author
didn't need them often after they were written.

I suspected as much - so I suppose it is the count since the new Hackage 2
implementation. That?s helpful to know.

Hello,
As for the queuelike package, I think its non-priority queue part loses
users to container's Sequence, monadic queues seem to at least partially
overlap in functionality with streaming libraries (pipes, conduit), and
priority queues are also implemented by a couple of packages
(priority-queue, pqueue). (also, I imagine not everyone likes the type
class + implementations style of programming.) Unfortunately, Hackage is a
bit of a mess. I've started programming in Haskell years after the last
version of queuelike was uploaded, and today is the first time I've heard
of it. The last time I needed a queue I've used Sequence, and when I was
googling for priority queues I didn't see any mention of this package. I
figure it being filed under "Algorithms" and not "Containers" also doesn't
help things.
As for the 0.* versions, as it was said, people in general seem not to pay
attention to the numbers, and only bump the major version when they make
some really significant change, or they run out of comfortable minor
version numbers. Hackage's package versioning policy insists only on
bumping the minor version number for breaking changes.
Best regards,
Marcin Mrotek

FWIW, I recently looked at the "packages by category"[1] page on Hackage and
found it more or less completely useless. There are far too many
categories. Some categories do appear with their singular and plural
forms, and many packages seem to be filed at least unexpectedly into a
category. I gather this mess has developed because categories have
been added over time. Does Hackage have an "override" file for package
provided data?

I suggest simply asking the list. You should get a few opinions,
especially for "vital" packages, as long as you are precise about what
you need. If you're lucky, sometimes the actual authors/maintainers
will respond. If you're even luckier, you might get a response from
one the champions of our community. Most of these opinions should come
with some reasoning/justification. Sure, they're just anecdotes, but
the commentary can be far more useful for making a decision than the
relative number of downloads.
