Re: ... efficiency (was Re: class implementation)

Performance with ... Is a mixed bag.

Mike is correct that introducing the iterator function -- even as useful as
it is -- brings in memory allocation costs and hence is a lose for small
numbers of arguments.

My concern is that the standard idioms for iterating over varargs have
essentially quadratic time complexity and that's basically a problem waiting
to happen.
