Hi,

Hi!

See attached patch+phpt; Any objections to include it in 5.4?

Yes, same objections as for other static typing.

Those objections do not apply here IMO.

IIRC, the main objections were that if we introduce strict hints for scalar values, then we start rejecting stuff that would "just work" via implicit conversions before. i.e. "2" vs 2.

In this case, if you don't provide a valid callback to a function expecting a valid callback, there is no way it will "just work".

Just like with other type hints, if you write function foo(A $b) and pass B which is not a subtype of A, there is no way foo() will "just work", as there is no way it will be able to interpret the value, an object of type B, as an object of type A.

+1 from me, this seems very useful.
