to function

This is wrong code:
void foo(int function(int) f) {}
void main() {
foo(x => 0); // OK
foo(x => 0.0); // Error
foo((x, y) => 0); // Error
}
DMD 2.064alpha gives:
test.d(4): Error: function test.foo (int function(int) f) is not callable using
argument types (void)
test.d(5): Error: function test.foo (int function(int) f) is not callable using
argument types (void)
I suggest to try to generate better error messages here, that better explain
the problem to the programmer.
