same question with how to wrap a gc function inside a nogc shell, if not, allowing a flag -ignore_nogc that'd enable this (again, for debugging purposes)

If you wrap the call in a debug block, it will work.

int foo() pure
{
   debug writeln("yep, this works");
}

Sorry for the extra noise.

just filed https://issues.dlang.org/show_bug.cgi?id=18407
Issue 18407 - debug should escape nothrow, @nogc, @safe (not just pure)
