Hi Philipp,

Yes, that should be ok, I think.

Thanks. Looks like it does what I want.

Yes, it does. I think there is no problem with this new behavior (well,
unless you either try to make use of old-style backquotes, or need the
semantics of old-style backquotes to transform old code that makes use
of old-style backquotes - I don't need to support these cases).
Thanks,
Michael.
