//////////////////////
module a;
import std.typecons;
alias Tuple!( float ) foo;

//////////////////////
module b;
import std.typecons;

//////////////////////

Compiling with "dmd a b -unittest" gives the following output:

E:\DMD\DMD2\windows\bin\..\..\src\phobos\std\typecons.d(424): Error: static
assert  (is(Tuple!(string,float) == Tuple!(string,float))) is false

instantiated from here: Tuple!(string,float)

instantiated from here: slice!(1,3)
