Re: [bug-gawk] Grammar improvement

[arnold]

Hi Valentin.

This note is to acknowledge that I got your message. I will try to look
at your work but as gawk is a background activity for me, I can't promise
when exactly I'll get to it.

Something that is a current consideration is that the gawk grammar should,
in theory, work with other yacc compatible programs (original yacc,
Berkeley yacc).

However, it may be entirely reasonable to reconsider that, since the
only one who should be running the parser generator is me. :-)

So, (a) thanks for this work, it looks interesting and valuable and (b) I
will try to get to this, but no promises as to when.

Thanks!

Arnold
