Hi Barry,
Yes, the builtins on the LHS of a forward rule will not run until the
triple patterns match. It's only when there's a binding vector from the
tree of patterns that it gets submitted to the builtins. Which makes
sense if you think of LHS builtins as normally being guards.

Hi all, I am working with forward rules for a project and I noticed that the
print(...) builtins in the LHS of a forward rule only get executed when the
full LHS matches. I was expecting the LHS to be matched in a per triple/builtin
manner and so the print(...) builtins get executed until a triple or builtin
did not match.
Can anyone confirm or deny that this is indeed the way the forwardRETE engine
works?
Kind regards, Barry
