[rules-users] "from" facts - working memory

Hello, My understanding was that facts evaluated using the "from" statement were not really facts and therefore were not stored in WM, therefore in: $event1Provider : Event1Provider() Event1(..) from $event1Provider.evaluate() the value of $event1Provider.evaluate() will get gc'ed (providing no other object has a handle to it). However I read in the forum topic "Why Using "from" Always Return A New Fact?" a post by Edson Tirelli which seemed to indicate that fact handles are created for values returned from the "from" statement, are these stored in WM? Do these values explicitly need to be retracted to avoid them accumulating in WM? Or is it the case that previous values are automatically retracted on recalls to ".evaluate" if they are !equals?
