See also NG discussion:
http://forum.dlang.org/thread/gltqflqrvsxggarxjkde forum.dlang.org?page=5

So address of label can be taken via some asm trick:

size_t address;
asm{
call L_label;
add EAX, 4;
move address, EAX
}
//OK now address points where needed

...

L_label:
asm{
move EAX, [ESP];
ret; 
}
//<<--- want code pointer here
....

The request is to allow direct use of label addresses in contexts other then
jump/call:
lea, mov,  etc. 

An extension of that would be to introduce taking of label address in normal D
code to aid portability, but that's the whole other question.

This bug has been closed as a duplicate of issue 1829, any updates and
discussion should go there.

There is also a list of definitions for the severity level here: (although the
priority level is mostly ignored)
