Hi I have following issue:
code:

import std.stdio;

import std.container;

alias HierarchyGraph HGraph;

class HierarchyGraph(T)
{
     T leaf;
     alias leaf data;

     HierarchyGraph parent = null;

private:

     Array!(HierarchyGraph) child;

}

int main(string[] argv)
{

     HGraph!int a0 = new HGraph!int();

     return 0;
}

Under 2.063 it compliles and runs.
Under 2.065 following error message given:

2.065 was installed with brew unde mac os lion.
2.063 from dmg package on this site

Any thoughts?
Thank you.

Same under windows. Is this compiler/phobos bug?

I can tell *why* it's breaking right now, but have been unable to 
understand what caused said breakage, or how it worked at all to 
begin with.

Will reduce and file (and potentially fix).

I fixed the implementation so that your test passes now. The 
implementation was... odd. I think it may have been "legacy code" 
from before we had "allSatisfy" and "anySatisfy" to easilly do 
introspection.

FYI, the issue was that "RepresentationTypeTuple" was eagerly 
called on input, regardless of type. Because you were operating 
on a forward reference, the RepresentationTypeTuple failed.

My fix consisted in calling RepresentationTypeTuple *after* first 
checking the current type.

I will submit the fix shortly.
