Are there any examples of "nom" being useful?
I find 'nom' to be useful if defined as "const id":
-- Given 'om'
om f m = (m >>=) . flip f
-- And 'nom'
nom = const id
-- And the natural name for a monadic version of 'no'thing
noM = return ()
-- We construct a useful example of 'nom':
eatCookies :: IO ()
eatCookies = om nom noM noM
:-)
Happy Friday,

The function is:

I have to admit my first reaction to this was that it isn't April 1st...
More seriously, "om" sounds useful but the name seems a bit obscure ("on monad"?) Are there any examples of "nom" being useful?
