\section2 member(variablename, position)
\section2 member(variablename [, start [, end]])
Returns the value at the given \c position in the list of items in
\c variablename.
If an item cannot be found at the position specified, an empty string is
returned. \c variablename is the only required field. If not specified,
\c position defaults to 0, causing the first value in the list to be
returned.
Returns the slice of the list value of \c variablename with the
zero-based element indices between \c start and \c end (inclusive).
If \c start is not given, it defaults to zero. This usage is
equivalent to \c $$first(variablename).
If \c end is not given, it defaults to \c start. This usage represents
simple array indexing, as exactly one element will be returned.
It is also possible to specify start and end in a single argument, with
the numbers separated by two periods.
Negative numbers represent indices starting from the end of the list,
with -1 being the last element.
If either index is out of range, an empty list is returned.
If \c end is smaller than \c start, the elements are returned
in reverse order.
\note The fact that the end index is inclusive and unordered implies
that an empty list will be returned only when an index is invalid
(which is implied by the input variable being empty).
