Nothing wrong, Pyste doesn't generate right code.

There are few possible solutions to the problem:

1. To use indexing suite v2:
http://language-binding.net/pyplusplus/documentation/containers.html
2. To use Py++, which will generate code that works:
http://pygccxml.svn.sourceforge.net/viewvc/pygccxml/pyplusplus_dev/pyplusplus/code_repository/array_1.py?view=markup
