The logic in the diagnostic here ended up doing a silent single step desugar through a typedef in the 'aka'.

I think the danger of doing that as you exemplify is that, if you don't know what context the printed type belongs to, then it's hard to make sense of the meaning of what was written.

If we have to step through a sugar node which carries context, like type aliases / using types and such, perhaps we should go straight for the canonical type instead.
