 The default behavior in dpath is to assume that the path given is a string, which must be tokenized by splitting at the separator to yield a distinct set of path components against which dictionary keys can be individually glob tested. However, this presents a problem when you want to use paths that have a separator in their name; the tokenizer cannot properly understand what you mean by '/a/b/c' if it is possible for '/' to exist as a valid character in a key name.
 
-To get around this, you can sidestep the whole "filesystem path" style, and abandon the separator entirely, by using lists as paths. All of the methods in dpath.util.* support the use of a list instead of a string as a path. So for example:
