Thanks for the pull request, and welcome! The Rust team is excited to review your changes, and you should hear from @Mark-Simulacrum (or someone else) soon. If any changes to this PR are deemed necessary, please add them as extra commits. This ensures that the reviewer can see what has changed since they last reviewed the code. Due to the way GitHub handles out-of-date commits, this should also make it reasonably obvious what issues have or haven't been addressed. Large or tricky changes may require several passes of review and changes. Please see the contribution instructions for more information. |

We should probably link to these types here.

Should be "in the presence"

Ok I've done the pertinent changes! Thank you all for your feedback :) |

s/know as/known as/
s/Aliasing/**aliasing**/ . Capitalization of common nouns is unnatural in English, and when it is done, it generally implies that the capitalized noun has a much more specific (and widely understood) definition than the lowercase noun (e.g. "Undefined Behavior" is not the same thing as "undefined behavior"). This is unnecessary for a word like "aliasing" which is already uncommon.
The reason I suggest bold here is because you are introducing a definition for it.

"in ___ in ___" reads a bit awkward. I might write:
Before: ...to permit mutability in the presence of aliasing in a controlled manner
After: ...to permit mutability in a controlled manner, even in the presence of aliasing.

Use period instead of comma after these parentheses.
Add comma after "threads".
Missing "it" before "is possible."
Don't capitalize (or emphasize) aliasing and mutation.

Ping from triage, @steveklabnik ! |

I am not likely to be able to review until late tomorrow, possibly tuesday. Sorry about that! |

@bors: r+ rollup So sorry about the delay, this is great. Thanks so much! |
