[Parsetree] Source locations in ParseTree?

[Werner Schuster (murphee)]

Just saw the news about Ryan writing a Ruby parser in Ruby, outputting
ParseTree.
Any chance that this will include source locations for each of the nodes?
(not just line numbers, but correct character locations).

JParseTree mixes in a source_locations method into the node-arrays, so
there's no need to open up the Array class.

Any thoughts/news on this?
