source that should compile, but doesn't
Create a variadic-template-function that takes a variadic-function-pointer as
its argument. This works as intended, and correctly accepts candidate functions
as arguments.
Create a typedef (via "using") for a variadic-function-pointer. This works, and
variables of this type can be correctly assigned to candidate functions.
Try to replace the variadic-template-function's argument type with this new
typedef. This should compile (at least, GCC accepts it), but doesn't.
This is somehow related to template parameter-deduction, even though explicitly
specifying the parameters still causes a "deduction" failure.
There's some more discussion on the stackoverflow topic link:
