split string for assign statements

[drom]

{ assign:[
  ["g0", "^ b0 b1"],
  ["g1", "^ b1 b2"],
  ["g2", "^ b2 b3"],
  ["g3", "= b3"]
]}

has to be equivalent to this:

{ assign:[
  ["g0", ["^", "b0", "b1"]],
  ["g1", ["^", "b1", "b2"]],
  ["g2", ["^", "b2", "b3"]],
  ["g3", ["=", "b3"]]
]}

Nice idea for a simplified text based format. I would just recomend a different seperator - maybe ';' would do it.
