--- Comment #1 from Basile-z <b2.temp@gmx.com> ---
this is a cool bug. The fact that this 3rd case passes explains it all:

  static assert(__traits(isSame, AliasSeq!(1, 1), AliasSeq!(2, 2)));

in traits semantic, the two args are actually a list that expands in place to (1,1,2,2) and finally what get compared is the two elements of what was the first trait argument !

awesome bug isn't it !!
