I notice that a lot of combinations are "hardcoded" in PEG.
E.g. a lot of constructs are followed by "free*" several times in the grammar where the first part of the construct remains the same.
Here is an experimental grammar:
And here are the stats:
http://pastebin.com/raw.php?i=ADTJ0KdTHere, "KE_clause free*" is used 11 times in PEG and even when "free*" doesn't follow KE_clause it could.
Why not move "free*" into KE_clause itself ? This would make the grammar easier.
"free*" is used ~200 times in the grammar. I'm sure this number can be lowered significantly.
Anyone is interested in joining such constructs into new variables?

"free" could be in "post-clause" together with "indicators", and then you would need to create a special post-clause-light for the few selma'o that can't take free as modifier (PA, BY, tenses and connectives, I think). Most occurences of "free" are after a selma'o clause.
"free*" is used ~200 times in the grammar. I'm sure this number can be lowered significantly.
To just one if "free*" was allowed wherever "indicators" are. The rationale for the restrictions on "free" was never very clear to me.

In the original YACC grammar, it was simple. I tried adding "free

modifiers" after every construct, one at a time, and excluded it where
the YACC program found an ambiguity problem.
