Asserting that list fusing kicked in

[Joachim Breitner]

Hi,

for those of you who don’t follow Planet Haskell and haven’t seen my
blog post¹ on it:

I have created a (very) small library list-fusion-probe with an identity
function

        fuseThis :: [a] -> [a]
        
that will complain loudly (at run-time, for the time being) if the
argument is not fused away. Using it might give you more confidence in
that your code really fuses as well as you think it does.

Greetings from TFP (where the invited talk by Geoffrey Mainland inspired
me to write that),
Joachim
