* Scope stuff
*
-* // FIXME - I need this to do next() without doccomments..
-*
-*
-*
-* Need to make this alot simpler...
-*
-* so debugging is possible.
-*
-*
-* at present it just runs along the stream and finds stuff then calls parseExpr .. etc,,
-*
-*
-* It would be better to parse blocks of code rather than the whole stream..
-*
-*
+* This code now uses the collapsed tree
