You can take this step even further:

The builtin functions (that aren't doomed for py3k) can be classified in
those groups:

A. Constructors for built-in types

basestring, bool, complex, dict, file, float, int, list, long, object,
str, slice, tuple, type

These cannot be made attributes of some object.

B. Functions that can be attributed to some class or module

abs, divmod, round, pow -> math

ord -> str
In consequence: [uni]chr -> int
hex, oct -> int

super, *attr, isinstance, issubclass -> object

hash -> sys?

C. Functions that could be made attributes of lists/sequences

max, min, len, enumerate, sum

But that would require to implement them for all sequence types or
implement a common basetype 'seq'.

D. Other functions I cannot attribute to a class

eval
globals, locals, vars
iter
property
classmethod, staticmethod
cmp
[x]range
repr
__import__
