It should now be at its alphabetical position.

Also fixed link to `TyCtxt` anchor.

 <span id="tag">Tag</span>                      |  The "tag" of an enum/generator encodes the [discriminant](#discriminant) of the active variant/state.  Tags can either be "direct" (simply storing the discriminant in a field) or use a ["niche"](#niche).

 <span id="tls">[TLS]</span>                    |  Thread-Local Storage. Variables may be defined so that each thread has its own copy (rather than all threads sharing the variable). This has some interactions with LLVM. Not all platforms support TLS.

 <span id="ut">uninhabited type</span>          |  A type which has _no_ values. This is not the same as a ZST, which has exactly 1 value. An example of an uninhabited type is `enum Foo {}`, which has no variants, and so, can never be created. The compiler can treat code that deals with uninhabited types as dead code, since there is no such value to be manipulated. `!` (the never type) is an uninhabited type. Uninhabited types are also called "empty types".
 <span id="upvar">upvar</span>                  |  A variable captured by a closure from outside the closure.
