Subject Re: Retrieving indices of repeated closures
Date Tue, 27 Mar 2001 20:10:20 GMT
I had started to do this as you recc.(with Vector), but I'm curious as to
why you say not to initialize until I have 2 + elements?  For efficiency?
I agree it'll save a little bit of time, but I can't imagine it would be a
huge slowdown.  But I very well may be wrong, and I'll try to do it in the
most efficient manner anyway.
