    @djspiewak Just listening to your type inference problem on SW#29. Was it a dealiasing problem with dependent types?

        @propensive Nope. Type constructor inference in three (or more) nested type constructors.

        @propensive So basically, F[G[H[_], A]] where F and G are known, infer H. It fails.
