I'm probably missing something obvious here...

The first line in your example defines an integer variable called "foo"
The second line defines a function called "fn", which takes an integer argument
and returns an integer. The name of the integer argument of "fn" should have no
significance at all in the current scope, but only inside the body of "fn"
itself, correct?

In short, whether I write
int (*fn)(int foo);
or
int (*fn)(int bar);
or
int (*fn)(int);
should make no difference (as far as I understand C++, and I could certainly be
wrong ...)
