In the documentation for Data.IntMap updateMin, a piece of example

Couldn't match expected type `Maybe a'

In the expression: a
In the expression: (5, a)
In the first argument of `fromList', namely `[(5, a), (3, b)]'
As a side note, the sort of operation implied by the example code was
really what I was looking for in the documentation -- but such a
method no longer exists in IntMap. ::sad::
Who do I tell this to / how do I ask to get it fixed?
Open a ticket in the ghc trac:
http://hackage.haskell.org/trac/ghc/
set the component to libraries other. Paste in your description and if
you can, attach a darcs patch to the ticket.
More generally, to work out where to send things check the hackage page.
Most packages list a maintainer or author and some are now specifying a
bug reports url.
Currently for the containers package it's not all that helpful, it only
lists a maintainer email address as librar...@haskell.org. Though that
would also have been a place to start to get the above advice. The next
release of all the core packages will also list their bug-report urls
and these will appear on their hackage pages.
