Indeed, using 'globals()' and 'locals()' works. However,
both report the same underlaying object, which is a bit
confusing. (Under what circumstances does 'locals()' return
not the same object as 'globals()' ?)

The problem appears to be that

exec f in a, b

where a and b are distinct dictionaries, does not look up
symbols in 'a' when in local scope.
I filed a bug report (#1167300).
