I'm pretty sure there's a random sentence generator in the Icon library;
it may even be an example in the book. Look around in the anonymous FTP
account on cs.arizona.edu, /pub/icon.


Note that a random sentence generator is perfectly happy with non-LR
grammars, ambiguous grammers, what have you - there's no reason to use a
YACC'ified grammer, just use the "natural" BNF. (The only restriction is
that you have have to "weight" recursions to keep the expected length of
outputs finite. This doesn't in any way change the language.)
