Of course it is better than the status quo, but if it does, the bug 
report should stay open, and/or a few new ones should be filed. The pull 
ignores the discussion about what would be a good design and implements 
the rather awkward semantics that are quickest to hack into the compiler 
instead.

Also, the proposed rewrite does not fix the problem. (I haven't tested 
it, but AFAIU, the following code is neither rejected by the pull, nor 
does it print "123".)

import std.stdio;

void main(){
     string text="123";
     void foo(){
         import std.conv;
         writeln(text());
     }
     foo();
}


(Also, essentially the same logic occurs in three distinct places in the 
new code.)
