Oops, attachment didn't get through.  Since Google Groups doesn't have
pages anymore, we need a scratchpad.

Any suggestions?

I've updated my 'safe_array' (for which, read 'safe_list') which goes
through some contortions to avoid accidental nil insertion, so that
there are explicit append() and insert() methods; there should also be
a remove() method. Nice example of the proxy pattern, probably not
very efficient, but I'll work up a benchmark.
