Tim Chevalier e3a68e235c Bring back "pred" syntax for writing predicates for check ... This commit reinstates the requirement that the predicate in a "check" must be a manifest call to a special kind of function declared with the new "pred" keyword instead of "fn". Preds must have a boolean return type and can only call other preds; they can't have any effects (as enforced by the typechecker). The arguments to a predicate in a check expression must be slot variables or literals.		2011-05-05 11:26:07 -07:00
