GHC's lexer (function Lex.mk_var_token) treats names starting with
an underscore followed by an uppercase letter as a constructor (conid)
and not as a variable (varid):
module Foo where
data T = _ThisWorksAlthoughItShouldNot
_ThisShouldWorkButItDoesNot = '?'
A comment in the source code tells something about syntax in interface
files, but I don't have clue... Could somebody (SimonM?) explain why
this is done that way?
Cheers,
Sven
