We could implement it that way, but it may not be the best way. There
is generally no advantage in defining a command simply to call a
variable and have modes change the variable instead of the key's
binding.
Possible drawbacks include:
* It is extra work (even if not very hard work). It is extra churn.
* It means the doc string can't be adapted for a specific mode.
* It means that a specific mode can't add features to the command.
I set up function variables for indentation operations because they
are _not_ equivalent to the user-level commands. Rather, they are
lower-level operations, and some of the user-level commands call them
multiple times.
These variables made it possible to have indentation commands which
did nontrivial work in a mode-independent way by calling the
variables' values.
However, over the years, some modes needed to replace the generic
indentation commands with specific ones.
Does this apply to sending code to an interpreter? I don't know.
Perhaps there is some sub-operation for which it would be nice to
define such a mode-set variable. But that is another issue.
