Description David Nadlinger 2013-03-16 03:30:03 UTC 
As per http://forum.dlang.org/post/kibnaskimiqnmzziegjo@forum.dlang.org, the following snippet should not compile:

---
void* delegateToPtr(void delegate() dg) {
    return cast(void*)dg;
}
---

DMD currently returns the delegate context pointer.

As I couldn't find any justification for this in the spec, I marked the issue as an »accepts-invalid« bug, but feel free to downgrade it to an enhancement request.
