Erm... plain namerefs to a variable tree (e.g. compound variable which
contains an array of compound variables etc.) should work properly now.
What you can't do is to use a nameref _within_ a compound variable (e.g.
$ typeset -C foo=( nameref x=blabla ) # ) - that will never work for
various reasons (one being problems with recursion (e.g. nameref
pointing to a parent variable) and the 2nd is that the ${!x}-style
syntax would be ambigous).
