import std.exception;
import core.exception;
import core.stdc.stdlib;

void foo() { }
extern(C) void cFoo() { }

void main()
{
    auto p1 = enforce(malloc(10), &foo);
    auto p2 = enforce(malloc(10), &cFoo);  // error

    // example use-case
    // auto p = enforce(malloc(10), &onOutOfMemoryError);
}

The constraint on enforce is:

-----
if (is(Dg : void delegate()) || is(Dg : void function()))
-----

I guess we need some kind of trait to fake the calling convention to be D in order to compare it against the type, such as:

-----
if (is(ToExternD!Dg : void delegate()) || is(ToExternD!Dg : void function()))
