[cut]

in PyPy, typeobject.py and typetype.py contain roughly 1000 lines of RPython 
code (to which we must add the related logic which is somewhere else).
In CPython, typeobject.c contains about 6000 lines of C.

Honestly, I doubt a that 100 lines of javascript code can make a python 
compliant type().
