Oh sorry, ##values? actually exists in Gambit. It was not reachable from my environment the other day, this is why I asked now. Thanks

Hi,

Is there any typecheck for (values) ?

I.e. something like

(define x (values 1 2))

(##values? x) => #t

(I'm aware that typecheck procedure would be Gambit-internal.)
