Comment(by simonpj):

 There is a lot of traffic about this on Haskell Cafe http://www.mail-
 archive.com/haskell-cafe at haskell.org/index.html#82264.  There seems to be
 enthusiasm, but also plenty of discussion of variants and alternatives.

 My own gut feel is that it's a lot better to have an initial symbol to say
 "here comes a function". So I'm keener on the multi-clause lambda idea, if
 someone can devise a syntax that works.  GHC's internals assume a multi-
 clause lambda anyway, so it's more or less just a syntactic issue.
