[ncl-talk] Possible bug (?) with lists in 6.2.0

[Kyle Griffin]

I'll further this request, if possible. Whenever I foray into using lists,
often in conjunction with loops, the variables are often reassigned or
otherwise change/lose their values. While Brian's initial code appears to
the desired functionality, it does not seem to work with the newer releases
and this has deterred me from utilizing any list features in my code.
Although my memory is fuzzy with a few years of rust, I think the original
functionality mimic's that of Java's lists, which would be nice to have.
