Subject: [ruby-talk:9716] Name of iterators for trees?

Hi,

Iterators is a nice concept and I'm trying to apply the idea to trees. 
However, I'm not sure how to name things. Should "each" be a depth-first, 
reversed-depth-first or even a breadth-first iterator? Should it be 
parameterized so that the user can specify the node-visiting order? Anyone 
seen any work/a good design on/for this? Whats a "natural" naming?

my_tree.each(:DEPTH_FIRST) {|node| ...}
or
my_tree.each_node_depth_first {|node| ...}


Regards,

Agnot
