Suppose I write something like this:
foo :: [Int] foo = concat (replicate 4 [4,7,2,9])
The value of "foo" is completely determined at compile-time. So, will the compiler generate calls to concat and replicate, or will it just insert a large list constant here?
To add to what others have said, you might want to read the Simons' paper "Secrets of the Glasgow Haskell Compiler Inliner": http://research.microsoft.com/~simonpj/Papers/inlining/ It's pretty accessible, and talks about the various knobs that can be twiddled in order to influence the black art of inlining.
