Subject: Splitting a string with escapable separator?


I'm trying to come up with an *elegant* way to split a string into an
array at a separator with the additional feature that the separators can
be escaped. It should work like this

  "Hello\, World,Hi".split_escapable(',' '\')
  # => ["Hello, World", "Hi"]

Through a number of permutations with regexps, scan and the rest of the
family, I was unable to find a solution. I could parse the given string
myself, going though it character by character, but I'd prefer a less
pedestrian approach.
