Plus, it means writing and reading the name 3 times instead  of 1. This 
is not much of an issue for 'f', but it is for names like 
'modify_x07_with_qz46pt'. Names like this occur when interfacing to 
external systems that dictate the names needed (as when interfacing 
Python to Objective-C  on Macs).
