It'd depend a lot on the details of what you propose, I think. True
variables seem like they'd be rather invasive, not to mention possibly
error-prone (is "foo" a variable or a column reference?). However you
could do something pretty self-contained in the form of a couple of
functions. I'd suggest they support more than just one variable, btw.
How about "set_session_variable(varname, varvalue)" and
"get_session_variable(varname)"?

I should think we'd at least accept that as a contrib module; whether it
would become mainstream would probably depend on the level of interest.
