The following does not compile:

---------------------------
class foo(T: T[])
{
}

class bar(Tp: Tp[])
{
}

alias bar!(char[]) cbar;

void main() {}
----------------------------
It gives the error message:
template instance bar!(char[]) does not match any template declaration

Renaming T to Tp, or Tp to T (or removing foo altogether) removes the error.

I'm on linux using dmd 0.101.
