We could fix this, I think, but I prefer the more direct approach
that you suggest below, if it works.  The wrappers are there to support
"lazy" quoting, so that % arguments like locals() would work without
quoting everything in advance.  For the format() function, I think we
could get by with simply quoting the arguments that are provided.

Let me know if you discover any problem with your python
implementation.  If I get time, I'll work on a C version and we
can include the new format() in the next QPY release.

Thanks for thinking about this.
