Andrew Sutton <andrew.n.sutton at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |andrew.n.sutton at gmail dot com --- Comment #3 from Andrew Sutton <andrew.n.sutton at gmail dot com> --- This is one of our x-fail tests. When you instantiate a constrained alias with dependent arguments, you have to propagate its constraints (somehow) into the resulting type. And of course, those can accumulate through multiple instantiations of aliases. Unfortunately, I'm not that familiar with how aliases work.
