Hi Dave, I like your proposed extension.
IIRC, the main invariant that we wanted to uphold is that callable objects are always instanceof Function, which continues to hold under your proposal. Again, repeating what you said: even without this extension, function proxies are already powerful enough to act as if they inherited from a custom prototype P, except that they can never claim to be "instanceof P". I don't see any reason for disallowing this if P inherits from Function.prototype. Mark may remember more details though. 2011/2/24 Dave Herman <dher...@mozilla.com> > > > David Bruant <bru...@enseirb-matmeca.fr> wrote: > > >Ok... hmm... well... > >I misread your initial post.
