performance of tuple-less Python?

The relative performance would be related to the performance 
of malloc on your system. You could get some idea by timing 
creating and manipulating sequences of various sizes in 
regular Python.

They're only redundant if the concept of mutability is 
meaningless. A reference-based language without a concept 
of mutability would be, um, an adventure.
