 of callbacks with a name.
```

## struct Any*
```go
type Any* = interface{}
```



## struct Callback*
```go
type Callback* = fn(ctx: Any) 
```



## struct Signal*
```go
type Signal* = []Callback
```



## fn register*
`fn register*(name: str, callback: Callback) {`

Registers a callback to a signal. There is no need to explicitely create
signals.


## fn emit*
