Thomas Lockhart should speak up - he seems the only person who
has objections yet. If the proposed thing is to be declined, something
has to be applied instead in respect to lexer reject feature and
accompanying size limits, as well as grammar inconsistency. Seems there
are only awkward solutions as alternatives. As you probably remember,
the proposed change only breaks constructs like 1+-2, which anyone
in a sane condition should avoid when programming :)

There are more size restrictions there. I noticed (by simply eyeing the
lexer source, without testing) that in case of flex lexer 
(FLEX_LEXER being defined in scan.c) lexer can't
swallow big queries. You (Tom and Michael) aren't using flex,
are you?
