Implement :exists? existential quantifier #8

Open amattsmith opened 15 years ago

amattsmith commented 15 years ago

An ‘exists’ keyword in the DSL would represent an existential quantifier that checked for the existence of a a particular pattern in working memory. The rule would then be satisfied only once if that pattern is matched. This is as opposed to firing ‘for each’ by default.
