Absolutely not. I, too, would be horrified.
Perhaps you should post a code snippet. From your original post it
sounded as though you were calling an xtra function that returned a
value that you *expected* was going to be a list but was VOID. All I
was trying to say - and it sounds like you agree - is that if you
call an "external" function that returns data to you and you are
relying on this data to be of a particular type before proceeding,
then it's incumbent on you to type-check. Lingo is a loosely typed
language and so permits all kinds of slop.
Cheers,
