Hi Ter,
While I like any improvment to trees that would eliminate cycles you mention
at the end
" A further restriction is that you should not add the same tree more than
once if you want the getNextSibling() stuff to work. This would be too
expensive to enforce probably. "
If you cannot inforce correct tree construction then not bother change the
existing one. Tree contruction and manipulation has been the bane of my
work
with Antlr.
I want robust tree construction that will throw a useful error when I try
and do some thing silly or just don't understand what is happening.
