When I was a student, I heard about function points and got the
impression that, say, an addition was one function point, which seemed
to me a metric that's specific to some piece of code, and to evaluate
how many function points one needs requires a similar amount of effort
as doing an implementation, so it did not appear useful as an estimate
of the complexity of the task.
These days we have Wikipedia, so I checked that, and it appears that
function points are useful for classical form-report applications,
where the required effort is mostly in the forms and reports and can
be estimated from the specification of the forms and reports. I can
see how that might work.
However, for other applications I have no idea how to determine
function points for them. For example, I wrote a comparison of
programming languages based on a case study of several parser
generators with varying functionality
<http://www.complang.tuwien.ac.at/anton/euroforth/ef99/ertl99.pdf>.
Given the differing functionality of the compared parser generators,
it would be useful for that kind of study to get a number that
represents the functionality and can be related to the SLOC (source
lines of code) metric for the implementation. Are function points
usable for this kind of application?

Really? My experience with Haskell is that I get type error messages
that are hard to comprehend.
Closer to comp.lang.forth, Factor has type inference; we had a little
workshop at the Forth-Tagung this year, where we should write a few
programs; the type checker constantly hindered me in achieving what I
wanted to do, and most others had a similar experience. Bernd found a
solution that was accepted, but when I tried to use his ideas for my
own program, I ran into the type checker again; I think that Bernd
just found a hole in the type checker.
OTOH, C type checking complicates things, but is still simple enough
that I can get out of C what I want (or maybe I just have more
experience with it). So, yes, Haskell type checking is different, but
not in the way you imply.
