 ### Why is `#partial switch` needed when there is a catch-all `case:`?
 
-By default, `switch` statements which have an `enum` or `union` condition require the user to specify every case that the type defines. It is a very common mistake to forget to add a new case when a new variant is added in other languages, so Odin defaults to will tell the user of this mistake. If the user wants to explicitly opt-out of this behaviour, `#partial` can be applied to the `switch` statement directly to state that not all of the cases need to be specified.

 `case:` is the catch-all case which allows for anything not specified, which includes `nil` or even invalid cases (e.g. custom-user-values or corrupted cases). `#partial` and `case:` are orthogonal concepts which are used to achieve different things entirely. Each variant might be handled, but there might still be an invalid case not handled thus `case:` might still be required depending on the problem.
