This looks rather like ($), but backwards. I believe the F# name for
this operator is (|), which is also a legal name for it in Haskell.
Odd, since (|) alone isn't legal. Calling it (.) will confuse the heck
out of anyone who maintains your code though, and make any transfer of
code between your projects and other people's liable to introduce bugs.
I can also do
readFile readme.markdown . lines . length
by making
a . b = a .liftM b
infixl 9 .
Kinda annoying, but the option is there.
Now that looks more interesting. Another name for it is (=^), since
it is like (=) but lifts its right argument. I know the Fudgets
library uses ^ in operators for a similar lifting meaning.
