    Do you mean adding an &optional KEYBOARD-MACROS-TOO argument, so it
    would return non-nil even when called while executing a keyboard macro?

    Or do you mean distinguishing different non-nil return values, e.g.
    call-interactively vs. execute-kbd-macro (instead of just t)?

I was thinking of the former, but the latter might be a good idea.

    I don't know what you mean.  (interactive ...) returns a list of values,
    which are mapped to the lambda list symbols.

The `interactive' form, when evaluated, returns nil.
However, it holds one "argument", a form that can be evaluated
to produce a list of argument values.  It could hold additional
"arguments" which could be used for various purposes,
including to display the command's return value.
