Is the module containing `countAssocs' written as a literate file?
Or maybe using an indentation style where top-level identifiers
are indented by one character or more?  If so, then I guess this is
probably a known problem that we have already fixed for the forthcoming
release 1.10 (due approximately at the end of this week).

Essentially, hat-observe can only sensibly report information
about top-level functions, i.e. not locally-defined functions.
In currently-released versions, it checks for top-level-ness of an
identifier by the column position of its definition, which is rather
a hack and pretty error-prone.  From the next release, the top-level
information will be generated correctly by the compiler itself.
