It might be worth rephrasing this error message somehow, although I suspect
it's written to fit into existing error reporting machinery that's not easy
to adapt to fit the situation:  the location is not referring to "TestG b",
but to "a type" on line 49, which is expected/"generated" by the context
TestG b established previously.  You have to read pretty closely to figure
that out, though.
