How about going the other way around?

    if imported():
        break

    <do your main code>

Most of the time, people put the main stuff at the end of the script, so
this check can serve as a seperator, equivalent to what is sometimes marked
with '***********************' - snip the script here.

Of course, it is still possible to do

    if not imported():
        main()

I think it is at least as obvious as is_main(), and even more so for those
without a C-like background.

(Personally I'd prefer an `imported` magic variable but I guess that's out
of question).
