[Python-Dev] removing nested tuple function parameters (original) (raw)

I consider the current situation to be a consistency feature. To a first approximation, Python function calls 'pass' objects by name-binding:

param_name_list = arg_object_list

Disabling structure unpacking in this assignment would make the language slightly more complex. Someone else posted the same observation in c.l.p.

Another thought. By directly unpacking and not naming a sequence, one 'announces' that only the components are of interest and that nothing will be done with the sequence object itself.
