I'm not sure how to go about adding this, looks like engine.Set() is used for gauges :/

Maybe we can name it something different like UniqueSet and use another name for the main operation so it doesn't conflict.

so, something like this?

type Set struct {}
...

func (e *Engine) Unique(value string) { .. }

[achille-roussel]

Well we can't call the top-level type Set because it conflicts with the top-level function. Maybe this:

type UniqueSet struct { ... }

then using one of these function names:

func Count(name string, tags ...Tag) { ... }

func Push(name string, tags ...Tag) { ... }

func Put(name string, tags ...Tag) { ... }

func Touch(name string, tags ...Tag) { ... }

func Track(name string, tags ...Tag) { ... }

The name Unique for the function name is not ideal because it's not a verb, so it doesn't communicate well what the action performed by the function is.
