Re: [VOTE][REST-SPEC] Add list and load function endpoints

[Szehon Ho]

+1 (binding)

I think it would be nice to track a specific-name for convenience over
definition-id, so engines can refer to each overloaded version of the
Function.

But I guess that's a general addition to the Function spec, which I guess I
missed to bring at that point.

Thanks!
