I agree with Robert that if the lib provides hash-style access, that's
probably a cleaner way to go. Note, though, that if the hash needs a
symbol rather than a string, it will need to use quotes also, as I did
in my other post:

  object[:'tree-list']

Omitting the quotes would give a syntax error:

  $ irb
  >> hash = {}
  => {}
  >> hash[:tree-list]
  NameError: undefined local variable or method `list' for main:Object
