Joaquim,
do you think you can request a pull of your code here?
https://github.com/uBLAS/ublas/tree/ublas_feature0011_mvrange_interface_t7411/

Also a test case is necessary. Please follow a style like that:
https://github.com/uBLAS/ublas/blob/ublas_feature0011_mvrange_interface_t7411/test/test_assignment.cpp
since it integrates well with boost's auto regression test functionality.

  If you don't provide a test me or David will have to make one that 
will take more time.
