Sounds like an excellent way to waste somebody's afternoon when they
start to troubleshoot code that's using your function.  Over and over
and over we tell newbies who have questions about what something
returns or how it works

    "Start up an interactive session, and try it!".

If word gets out about functions like yours, we sort of end up looking
like twits.

Only the people who use your function. :)
