i was just wondering how many people would remember "Do Not
Taunt Happy Fun Ball".

yes, intentionally or otherwise.

as a rule of thumb, in GC situations, if you have a choice between
creating one large object or numerous small ones, one large object
will be more efficiently collected and reused. this is why in lisp,
rather than consing up a list, if you can reasonably use an array,
that's what you should do. the principle applies in general to any
programming environment.

there is a wacky subculture in programming of folks who think
that obscure code is somehow "better".
