Why say hoist when we can say return? I can think of several ways of returning values that don't require the caller to allocate a binding for the return value. Variants of the existing perl 5 stack push would work fine. We could also use a special "register" variable that return values are shoved into. None of these require the hackery of Tcl's upvar. Shouldn't we adopt a policy of never adding stuff to Perl 6 the language just because it'd be easy with a particular release of perl 6 the software? - Ken
