Two primitive features that would be useful for mumamo
(and perhaps othere programs) are:
* A primitive that would let-bind variables from an alist.
I think Common Lisp has such a construct; is that correct?
I do not recall its name, though.
* A way to temporarily turn off all buffer-local bindings. This could
take the form of a variable which you would bind with `let', and when
it is non-nil, the buffer-local bindings are not visible.
`with-current-buffer' should bind it to nil so that the buffer-local
bindings of the newly current buffer always do take effect.
It would be ok if certain variables whose values are stored directly
in the buffer object, such as `buffer-file-name', fail to be affected
by this feature.
I think any feature to temporarily switch modes, or pretend to do so,
would find these features useful. Could someone implement them?
