[Template-haskell] another TH panic

Yes, that's the right thing to do. 

I'm working hard on some GHC re-engineering, with a view to making (new
bits of) TH easier to implement.  In parallel, Tim is writing up notes
about our proposed changes to TH.  We'll put them out for comment
shortly.

Meanwhile, I'm hoping that no one is really stuck with any TH bugs. If
so, please make it clear -- otherwise I'm just collecting them.
Realistically, it'll be another couple of months at least before the new
TH iteration will arrive.
