[PYTHON MATRIX-SIG] Slices

[James Hugunin]

   From: hinsenk@ere.umontreal.ca (Konrad HINSEN)

   Another idea: introduce an object "index_expression" that can be
   indexed to get an equivalent expression. Then
      i = index_expression[2:4,...]
      a[i]
   would be equivalent to
      a[2:4,...]
   There would be no new syntax to learn; although users might have
   to know that index expressions are really tuples if they want
   to do something that is not possible with standard indexing.

Anybody who's interested in this idea can do the following under v0.35.

import Numeric
index_expression = Numeric.__slice_generating_class()
