By the way, thanks for everyone's comments so far!

Concerning: -- |> is like a UNIX pipe. infixl 9 |> x |> f = f x I find "ctx |> currTok |> tokenType" to be more readable than "tokenType $ currTok $ ctx" because you're not reading the code in reverse. That's my primary complaint with "." and "$". That's especially the case when I'm spreading the code over multiple lines: -- Translate a C type declaration into English. translate :: String -> String translate s = s |> createParseContext |> readToFirstIdentifier |> dealWithDeclarator |> consolidateOutput I prefer |> for readability, but I understand that it can be bad to spring new constructs on programmers in the middle of a program, and I'm totally in favor of following standard Haskell idioms. Does anyone else have strong opinions one way or the other? It seems like most of my program is centered around pipes of "|>", so it's an important issue.
