I see.  What would with-coding-system-for-write look like?  What
would functions look like that want to find out which coding system
to use for writing?

Maybe something can be abstracted so that

(with-variable 'coding-system-for-write 'foo
  ...statements...)

works for all variables.  Of course, you might as well call it `let',
then :-)
