Proof of concept:

https://github.com/aG0aep6G/dmd/commit/aa0563a49536e42fe9b2c1c2d540a7f1f1b075d4

With that tiny patch, this works:

----
void func(int x, int y)
{
     import core.stdc.stdio: printf;
     printf("%d %d\n", x, y);
}
void main()
{
     void delegate(int x, int y) dg;
     dg.funcptr = &func;
     dg(1, 2); /* prints "1 2" */
}
----
