This sentence reads a bit weird. Did you mean "prepend"?

(Hm, also there is a merge conflict now.) |

@ilevkivskyi this should be ready to try on another code base. I think I will tackle (finally) setuptools support next. It should be faily straightforward. |

Before merging this I also should probably update https://mypy.readthedocs.io/en/latest/command_line.html#how-imports-are-found (which I will do shortly). E: Done. |

As promised in #5227, here is an implementation for refactoring and making the search path compliant with PEP 561. The order is specified in https://www.python.org/dev/peps/pep-0561/#type-checker-module-resolution-order.
This is also my first PR from an airplane :)
