Comment(by megacz):

 Grr, in my previous post, "namespace" should actually be "lexical token
 class", and in my example (**) is a tycon, not a datacon.

 Apparently this still ''is'' confusing for me :)

 At the moment, if I understand correctly, {{{-XTypeOperators}}} considers
 symbols starting with a colon to belong to the tycon/type/datacon lexical
 token class ("upper case identifiers") while all other symbols belong to
 the expression/tyvar lexical token class ("lower case identifiers").  With
 -XSymbolsAreTyCons, does "starts with a colon" no longer matter?  That
 would be sort of nice.
