Oh, thank you for clarifying. I'd totally missed that.

No, there's no problem at all with pattern quotes. (I've just done the work and it took 10 mins.) I'm already messing with the TH stuff in pursuit of the quasi-quote changes I advertised, so I'll commit it at the same time.  That is

	TH pattern quotes will work
	but TH pattern splices will continue not to exist

Thanks for sorting out my misunderstanding.
