Hi Gurus,
I'm a novice using ANTLR for a development project. I am at a stage
where I need to rewrite AST so that the transformed AST renders itself
more easy for me to walk and emit the translation that I need. In this
context I've a concept question.

The only caution is that TreeIterator depends on parent pointers. I am
contemplating a version

Netbeans). I have a problem with COMMENT token.
Basic version for one line comment looks like this:
COMMENT :
'#' (options {greedy=false;} : .)* NEWLINE
;
But comment in Tcl starts only at the beginning of a line with
