Harry Ohlsen [mailto:harryo@qiqsolutions.com] helpfully remarked:

…
I know it’s a bit anally retentive :slight_smile: … but I prefer
references like this in alphabetical order, so I added a line:
…

if children[current_root] != nil

    children[current_root].sort! {|a, b| a.to_s <=>

b.to_s} # <---- THIS ONE

cool, too. very helpful.
