Steve and Stefan (and my name is Stef and was Stephan  ;-),

 From a pure programmers point of view you might be fully right.
btw I don't want to start a flame war,
but from a non-programmers point of view (which is a growing group, me 
falling somewhere in between),
reading the philosophy behind Python, I come to a totally different 
conclusion

 From what I remember some philosophical highlights are:
  Python should be intuitively, simple, universal and allow many 
solutions for the same problem.

To drive my car,
- I don't need to know the type of the spark-plug
- I don't need to know how many spark-plugs my car has
- I don't need to know if my car has any spark-plugs
- I might even have never heard of a spark-plug

To use Python,
- I need to know what an numpy array is
- I need to know what a numeric array is
- I need to know what an array array is
- I need to know what a scipy array is
- and maybe a few others ...

But I just want to use an array,
and I just want that the array always to behave the same,
even if I give the array to someone else.

Ok, a car has a much longer history than programming languages.
And "batteries included" is both the strong point and the weak point of 
a language like Python.

 From the viewpoint of the non-programmer,
who just wants to drive their car (without wanting to have a look inside 
the car),
there is still no good answer :-(

cheers,
Stef Mientki
