Hi 

I started to introduce a visitor for the ParseNode hierarchy. Based on this
visitor I wrote a pretty printer called Gutenberg (I moved all the print
related methods on visitor) so that we can create better and easy parse tree
wlaking and decorating tools.

Now I have a early beta pretty printer (just show code correctly not pretty
printed ;)) and a SQ00 syntax pretty printer (not even in alpha).

I would like to know what a selector only containing : ?

Then if you are interested contact me.
