Re: [Haskell-cafe] Why does (++ "!") "bla" return "bla!" and not "!bla"?

Hi all,

I'm going through the excellent http://learnyouahaskell.com tutorial. So far it's been pretty easy to follow but now I ran into something that (when I later started reading about maps) do not seem to fully grasp.

I think I'm close to understanding why (++ "!") "bla" returns "bla! instead of "!bla" but I seem to be missing the last step. :-) I noticed that ((++) "!") "bla" does indeed return "!bla". So it seems to be related to the infix property of ++? The types of (++) "!", ((++) "!"), and (++ "!") are all the same so that doesn't tell me much.

Would someone please nudge me in the right direction?

What can you say about ("!" ++) ? Stripping the infix, what is (++) "bla" "!" ? Conrad.
