It is quite unclear to me whether this is a real improvement, or not.
Well, let's say it _is_ an improvement, but it's not sufficent.  For
instance on

    vcsn.automaton('''
    context = "lal, q"
    $ -> 0
    0 -> 1 <2+2>a
    1 -> $''')

we go from:

    14.10-27: Q: invalid value: 2+2, unexpected +

to:

    14.10-27: Q: unexpected +
      while reading: 2+2
      while reading: <2+2>a
      while reading automaton: digraph
    {
      vcsn_context = "lal, q"
      rankdir = LR
      edge [arrowhead = vee, arrowsize = .6]
      {
        node [shape = point, width = 0]
        I0 F1
      }
      node [shape = circle, style = rounded, width = 0.5]

      I0 -> 0
      0 -> 1 [label = "<2+2>a"]
      1 -> F1
    }
