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()))
