We still need ctxt_prec, I think, to pass to the ordinary type pretty-printer, when we have HsCoreTy.

Shouldn’t the parens all be put in by HsParTy? I tripped over this when I mistakenly added what I thought were missing maybeParen calls for HsAppTy and HsAppTys, but that was flagged as an error by a test in tests/printer. So why are there /any/ maybeParen calls? Simon
