A C programmer wouldn't save and restore many variables, but rather
would swap pointers to structs (or, in the dynamic case, lists).  This
suggests that there could be a "mode-local" object: either a well-known
map in ELisp (which would require explicit lookups, as in the C case) or
a parallel to buffer-local variables in C.  One could even obtain it
from text properties at point.
