That's a good point! :)
Actually, the source text is parsed and an AST is built.
This tree is then rewritten using a tree grammar. The tree grammar
resolves some kinds identifiers to values from the environment, while
leaving other kinds of identifiers unresolved for later processing.
The rewritten tree is then passed through RMI for further processing in
The early identifier resolution needs to take place before transmitting
the tree over RMI, because that information is not readily available on
the other side.
So the tree I want to transmit is not necessarily the AST resulting from
just parsing the original source text.
