Here's the wiki page:
http://hackage.haskell.org/trac/haskell-prime/wiki/CompositionAsDot
Personally I think function composition is what Haskell is all about
and it is absolutely essential that the syntax for it be lightweight.
If we think using . as qualification as well as composition is
confusing, I'm much more inclined to say using it as qualification was
a mistake.
The comment on the wiki page about $ being more common in reality is
not even close to true for my own code, and I don't think I'm unusual
in that regard.
