Coroutine's license is unclear
coroutine/ start like this:
/* * This file is part of the "Coroutine" project and released under the MIT License. *
The problem is, there is no definition of "the MIT License" throughout the entire project.
ioquatix (Samuel Williams) can you add your terms somewhere inside of LEGAL? There are several other materials also under the MIT license. You can follow how they are listed up.
