The first token in "--:\n" is...
a) varsym, because varsym always wins according to section 2.3:
An ordinary comment begins with a sequence of two or more consecutive
dashes (e.g. --) and extends to the following newline. The sequence of
dashes must not form part of a legal lexeme. For example, "-->" or
"|--" do not begin a comment, because both of these are legal lexemes;
however "--foo" does start a comment.
or b) comment, because the maximal munch rule says so (it matches the newline):
comment -> dashes [any<symbol> {any}] newline
varsym -> (symbol {symbol | :})<reservedop | dashes>
GHC says comment. Hugs says varsym. What's the answer?
