[antlr-interest] "Comments" token from source to the target language

[Andreas Bartho]

Hi,

I had a similar problem (getting a C#-AST with comments and Preprocessor 
directives). I settled with defining 3 parsers (C#, Preprocessor, 
Comments) and merging the resulting asts.

There are some ambiguities to be solved (e.g. does a comment above the 
first statement in a method belong to the method body node, the 
StatementList node or the first statement node?), but it saves you much 
hassle in your grammar definition (as already discussed).
