So this is similar to a light version of my suggestion. Just change
one function instead of all functions that are reading the buffer. I
am beginning to like the idea ;-)

"syntax-ppss" then need a table of chunks. And there must be a way to
quickly switch that table.

Could it look like a macro, something like "with-chunks"? Will that
take care of "inner calls" to syntax-ppss in a correct way?
