Er, no. : $foo.bar($baz); # looks in ref($foo), then falls back to MMD : : If this is correct, can we simplify the latter to mean "MMD only" ? : Would there be a more symmetric MMD only form? bar($foo, $baz) is the MMD form. However, MMD is defined to pay attention to lexical scoping, and if the innermost definition of the sub isn't multi, it reverts to ordinary sub dispatch. If the innermost definition is multi, then all multies out to a scope that is not multi are considered. Basically, all sub calls are inherently MMD, but ordinary subs are a degenerate wildcard case that hide any outer definitions. Larry
