---------------------------------+------------------------------------------
Comment(by michal.palka):
It seems that it's possible to simplify it further if `a` is exported.
Thanks to Nick Smallbone for suggesting this one.

module Main (a, main) where
a = \x -> seq undefined (+1)
main = do
print $ (a [] `seq` id) [0]
