It is said in documentation of std.traits module that "BaseTypeTuple!(Object)
returns the empty type tuple."

But in D 2.052 the follownig code fails to compile:

import std.traits, std.typetuple, std.stdio;
void main()
{
    writeln(typeid(BaseClassesTuple!Object));
}

The error message is:
<...>\src\phobos\std\traits.d(1772): Error: tuple index 0 exceeds 0
