The implementation for sys.implementation is going to use a new (but "private") type[1].  It's basically equivalent to the following: Does this really need to be written in C rather than Python? Yes, because we want to use it in the sys module. As you get lower down in the interpreter stack, implementing things in Python actually starts getting painful because of bootstrapping issues (e.g. that's why both structseq and collections.namedtuple exist).

sys.implementation could be added by site or some other startup file.
