The document reads "It is an error to return the address of or a reference 
to a local variable." in the section of Local Variables in function.html . 
But when i use dmd 0.112 to compile this:
<code>
import std.c.stdio;

int* f()
{
 int a;
 return &a;
}

int main ( char [] [] args )
{
 int* b = f();
 getchar();
 return 1;
}
</code>

it succeeded.
Is this an unimplemented feature or i've missed something?

Just because you got away with it, doesn't make it legal ;-)

That spec line just gives a future compiler a license to kill.
