$ ri ParseTree | grep string
      parse_tree, parse_tree_for_method, parse_tree_for_string, process
$ ri ParseTree#parse_tree_for_string
---------------------------------------- ParseTree#parse_tree_for_string
      parse_tree_for_string(source, filename = nil, line = nil, newlines
      = false)
------------------------------------------------------------------------
      Returns the parse tree for a string +source+.

      Format:

        [[sexps] ... ]
