Hi everyone,

This code works...
----------------------
import std.variant;
import std.stdio;
void main()
{
  Variant v;
  v = "hello";
  writeln(v);
}
----------------------

But this code does not...
----------------------
import std.variant;
import std.stdio;
void main()
{
  Variant[string] v;
  v["there"] = "hello";
  writeln(v["there"]);
}
----------------------
...resulting in this runtime failure:
core.exception.RangeError@Var(6): Range violation

What did I do wrong?

Using Digital Mars D Compiler v2.027, on OS X 10.5.6.

Thanks,
--Eljay

Is it this one?

Hey Eljay, thanks for being around :o). It's good you raise scrutiny about the dynamic style of coding in D. The code is correct but subject to a compiler bug:

I just voted that up (it's supposed to raise its informal importance), you may want to as well.

Thanks Andrei!

I'll put in in my vote.  :-)

I'm relieved that my program is correct (as per my understanding of the documentation).  And that the compiler bug will be fixed in due course -- I'm very patient.

Sincerely,
