Hi all,

When aliases are used I expect to see it names on compile errors. But when
I use:

 struct __Bulk(T) {
     T[] chunks;
 }
 alias __Bulk!(byte) Bulk;
 alias __Bulk!Bulk   MultiBulk;



The compilation error for:

 void question1() {
     Bulk("bad");
 }



is:

 bla.d(12): Error: cannot implicitly convert expression ("bad") of type
 string to byte[]
 bla.d(12): Error: structliteral has no effect in expression
 (__Bulk((__error)))



I expected to see (Bulk((__error))) instead of (__Bulk((__error))).

And the runtime output error for:

 void question2() {
     MultiBulk mb;
     writeln(typeid(mb));
 }



is:

 bla.__Bulk!(__Bulk!(byte)).__Bulk



Despite in runtime I accept don't see aliases name, if it is needed for
accomplish speed.

What are your opinions about these erros output?

Would be bad or hard dmd keep those information, and outputs like gcc "aka"?

It should be quite possible, but I have no idea how hard it would be. 
Regardless, it's not the kind of change I'd expect anytime soon, because the 
benefits are relatively minor in comparison to fixing bugs. The source is open 
on github for anyone to hack at and submit pull requests if they want to 
though.
