This code compiles, but I don't remember if this used to compile even before
fixing bug 7500 :
int outer(immutable int function(in int) pure foo) pure {
pure int

OK. Reduced test case.
int sqr(int x) pure {
return x * x;
}
void main()
{
immutable(int function(int) pure) ifp = sqr;
// Error: cannot implicitly

I think making inner() pure isn't necessary.
Following raises no error and works as expected.
T outer(T)(T function(in T) pure foo) pure {
int inner() {

I think making inner() pure isn't necessary.
In this program I want inner() to be pure.
