This has come up before, many, many times. There
are two answers. One is that there is, in fact, a
list method to return a length. It is list.__len__().
The len() global function calls this method.
All objects that implement the len() function
do it by implementing this 'magic method.'

The other is that what feels intuitive to one
person doesn't necessarily feel intuitive to
someone else with a different background, etc.
