: Logical negation. On the boolean type, this flips between `true` and
`false`. On integer types, this inverts the individual bits in the
two's complement representation of the value.
* `box`
: [Boxing](#pointer-types) operators. Allocate a box to hold the value they
are applied to, and store the value in it. `box` creates a box.
