Subject: inlining higher-order-functions? Newsgroups: gmane.comp.lang.haskell.glasgow.user Date: 2006-12-22 05:23:57 GMT (2 years, 28 weeks, 5 hours and 4 minutes ago)
I've just discovered the {-# INLINE #-} pragma, but it's not
doing as much for me as I had hoped.
My example is complicated, so let me present a simpler analogy.
Suppose I defined
compose :: (b -> c) -> (a -> b) -> (a -> c)
compose f g = \x -> f (g x)
I can easily persuade GHC to inline 'compose'.
But when 'compose' is applied to known arguments, I wish
f and g to be inlined in the body of 'compose'.
Is there a pragma that will do the trick?
(I attempted to put an INLINE pragma in a where clause,
but GHC was not amused.)
