CLU has only two flavours of cluster: mutable and immutable.
Procedure (and iterator) parameter passing is by sharing (rather than
value or reference) since there is no notion of value or reference, only
of the name of an object which may be one of many names.

The implementation uses pointers left, right and centre for practically
everything -- the exceptions might be int, char, bool and possibly float.
For the VAX implementation, the native VAX implementation--the
language is not interested in grubby pointers and references, only in names.
