Actually, I don't think(not sure about this though) that Ruby actually
knows, whether the number/string/whatever is in the literal(?) form, or
if it's a return value from a function, beyond the parser level.
Therefore, checking for it should be hard (or better yet, a waste of
cycles).

Personally, I think this warning should be allegated to the
 $VERBOSE == true  level. (Those would be much easier to ignore)

What I wanted to do was check if an array contained a certain value, and
do something with it, or else. Simple matter.

Just a mite obfusticated, if at all. So I think the stuff above made
sense... (It was short and to the point anyway (i think...))

But this is just going to be a matter that will be discussed my many
without anyone changing their minds (not really they won't).

I mean should we go for short elegant code irritating-waste-of-spacers.
Ha.
