# ms: metric spaces

A `MetricSpace`

is a set together with a notion of distance between
elements. Distance is computed by a function `dist`

which has the following
four laws:

**non-negative**:`forall x y.`

`dist`

x y >= 0**identity of indiscernibles**:`forall x y.`

`dist`

x y == 0 <=> x == y**symmetry**:`forall x y. dist x y ==`

`dist`

y x**triangle inequality**:`forall x y z.`

`dist`

x z <=`dist`

x y +`dist`

y z

See the Wikipedia article on metric spaces for more details.
