Re: Variant[Variant]

Hi Ali, thanks for helping me out.

Could you please provide a minimal program that almost compiles.

I uploaded a new version with a main routine. So you know, I am 
using DMD 2.063.2 on Fedora 15.

The code should compile with "dmd serialize.d".

I since realized that I was not dealing with a Variant[Variant] 
but a Variant(Variant[Variant]). It didn't seem to like having 
"[Variant]" called upon it.

After extracting it to a V[V] (called tcd1_vn), I noticed 
something else.

Doing a foreach on it,

  foreach (_a_, _b_;tcd1_vn)
  {
    writeln(_a_.type(),",",_b_.type());
    writeln(_a_.get!(string),",",_b_.get!(long));
  }

gives this:

  immutable(char)[],long
  a,1
  immutable(char)[],long
  b,2
  immutable(char)[],long
  c,3

So it appears that Variant("a") is a key, but

  assert(Variant("a") in tcd1_vn);

fails. Any ideas?

Thanks again for helping. I have been reading your online book. I 
have found it quite helpful.

Jason
