Why exactly is this now forbidden, too?

Punctuation?  Well, we already have ".flags", so at least here we do
have a real life use case.


I really would like to avoid new restictions of variable names,
especially as I cannot see any good reason for it - yes, your awk
script cannot handle this situation, but I tend to belive the fix is
in a better parser than in placing restrictions on the input data.

Best regards,
