I'm no expert on the subject but here are a few criteria for builtin method
inclusion:

* Useful - show many popular use cases, e.g. attach many links to various
lines on github/stackoverflow/bitbucket.
* Hard to get right, i.e. user implementations tend to have bugs.
* Would benefit greatly from C optimization
* Have a great, obvious, specific, readable name
* Don't overlap with anything else in the stdlib - TSBOAPOOOWTDI
* Consistent with the rest of python, e.g.
* Community approval
* BDFL approval
