Ugh, no. The ability to change the minimum index is evil.
Not always; it can have its uses, particularly when you're using the array as a mapping rather than a collection. Pascal had a nice feature where you could use any ordinal type as an array index, and sometimes it was handy to have things like an array indexed by the characters 'A' to 'Z', or the values (Red, Green, Blue). Typically you didn't need to do arithmetic on the indices in those case, though. Python addresses this by having separate types for sequences and mappings. -- Greg -- http://mail.python.org/mailman/listinfo/python-list
