| So you complain about how obscure this check is in C:
|   v += u;
|   if (v < u) overflow();
| but you're happy with this mess to not check in Lisp:
|   (locally (declare (optimize (speed 3) (safety 0))) (set v (plus v u)))
| !!!?!??!   Ha ha ha!

thank you.  I needed that.

Common Lisp programmers write macros that do these things for them.  this
is another important point you missed about the lack of abilities in C.

| memory that should never have been allocated in the first place, but is
| so conservative that it only frees a fraction of it?  Am I right or am I
| right?

you're wrong, and you're being silly, now, instead of witty, like above.

| This thread has turned into a farce.

yeah, funny how it just did, isn't it?
