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.
