Discussion:
The original bind proposal gives the guarantee that tr1::bind(f, t1, ..., tN) does not throw when the copy constructors of f, t1, ..., tN don't.
This guarantee is not present in the final version of TR1.
I'm pretty certain that we never removed it on purpose. Editorial omission? :-)
[ Berlin: not quite editorial, needs proposed wording. ]
[ Batavia: Doug to translate wording to variadic templates. ]
[ Toronto: We agree but aren't quite happy with the wording. The "t"'s no longer refer to anything. Alan to provide improved wording. ]
[ Pre-Bellevue: Alisdair provided wording. ]
TR1 proposed resolution:
In 99 [tr.func.bind.bind], add a new paragraph after p2:
Throws: Nothing unless one of the copy constructors of f, t1, t2, ..., tN throws an exception.
Add a new paragraph after p4:
Throws: nothing unless one of the copy constructors of f, t1, t2, ..., tN throws an exception.
Proposed resolution:
In 22.10.15.4 [func.bind.bind], add a new paragraph after p2:
Throws: Nothing unless the copy constructor of F or of one of the types in the BoundArgs... pack expansion throws an exception.
In 22.10.15.4 [func.bind.bind], add a new paragraph after p4:
Throws: Nothing unless the copy constructor of F or of one of the types in the BoundArgs... pack expansion throws an exception.
