Thank you for answering :) Could someone tell me where C++ Standard
mentions this form? I have looked up C++ standard 2003, but can't find
it.
Which form are you referring to?
I think Universe was referring to the form of declaration of the
argument like this:
int bar(double); // declaration of a function
int foo(int blah(double) = bar)
{
// here 'blah' is the name of the argument
// where a declaration that otherwise would be a function
// degrades into a pointer-to-function
return blah(3.14159);
}
I don't remember exactly where in the Standard it is, but I am fairly
certain that it's in the same approximate place as in the new Standard,
of which one can find a draft version on the Standard Committee's page.
