This reminds me, what symbols are valid for Haskell operators? I know 
that function names are:
(in regex format) [A-Za-z_'][A-Za-z0-9_']*, but does that Haskell report 
define a definitive list of symbols that can be used in Haskell 
source... and how does that relate to the character set... can any 
symbol be used?
