Yes, they would. I don't think using the prefix argument is easier to
use here. We use separate commands in Emacs Lisp, and I prefer the same
key bindings as them. (I could customize them, though.)

Probably you are right. A variable in a language other than Lisp or
Scheme cannot have a value within Emacs, so especially describe-variable
may not be useful for those languages... I would prefer to type C-u M-:
to choose a language (and default is decided by major-mode).

Possibly. We need to discuss this later on.
