Hi Folks,



Ignore if you are busy.



I am coding some with PEGParser and it appears that something called a ParserTree is a collection of nested collections of nested collections....all the way down .



That, presumably gives the tree.



The interesting question, is "how using Smalltalk Collection messages do you implement the various Tree traversal strategies?"





I see Ducasse has written a bit on it http://stephane.ducasse.free.fr/FreeBooks/InsideST/InsideSmalltalkNoOCRed.pdf



Again, feel free to ignore; I don't want to waste your time, I just think its really cool that Collections can act as a Tree (back in the C days, I believe they where all pointers to this and that)



cheers,



tty
