[antlr-interest] "!" operator and hidden tokens

[johnj1984]

Hi, thanks all for the suggestions for examples of source to source 
translation. Excellent reference.

Now I have a question with regards to maintaining comments: 
  When using CommonASTWithHiddenTokens ast nodes, does the "!" 
operator transfer the hidden tokens to the surrounding non-matched 
nodes? When I am iterating through a tree that has some of the 
original nodes "!" out, I don't seem to be getting any comments, 
although the filter.getInitialHiddenToken() method correctly returns 
the first hidden comment.

 If the "!" operator does not link the hidden tokens to the 
surrounding tokens, what is the general strategy for dealing with 
this? Override the match() method  to copy the links?
  
  Also defined as, are there any examples of spitting out comments in 
across AST tree translation/manipulations?

  Thanks, johnj1984
