You're right: `setq' is also destructive.  But it's slightly different (the
difference has to do with the notion of "pointer aliasing").

In Scheme destructive operations are traditionally named with a "!" suffix,
so `setq' is actually called `set!'.

As for me, I'd rather get rid of `setq' and `set!' altogether.
That's basically what SSA does behind the scenes ;-)
