-// This is an example where the older inference algorithm failed. The
-// specifics of why it failed are somewhat, but not entirely, tailed
-// to the algorithm. Ultimately the problem is that when computing the
-// mutual supertype of both sides of the `if` it would be faced with a
-// choice of tightening bounds or unifying variables and it took the
-// wrong path. The new algorithm avoids this problem and hence this
-// example typechecks correctly.
