Hi,

Sorry, my wording was too ambiguous.
Of course #t always 'works' in the sense that it finds the
maximum positive integral key for arrays without holes. It
doesn't matter if there are other keys, too:
print(#{ 0, [1.5]=0, 0, [2.5]=0, foo=0 }) --> 2
My point was that newbies could easily be lead to the wrong
conclusion that table.maxn is the standard way to get the length
of a table. But it's only a fallback for exceptional cases.
Bye,
Mike
