^title Fn Class

|
^category core
|

|
|
|
||
|
|
A first class function—an object that wraps an executable chunk of code.
|
||
|
|
[Here](../functions.html) is a friendly introduction.
|
||
|
|
|
||
|
|
### new **Fn**(function)
|
||
|
|
|
||
|
|
Creates a new function from... `function`. Of course, `function` is already be
|
||
|
|
a function, so this really just returns the argument. It exists mainly to let
|
||
|
|
you create a "bare" function when you don't want to immediately pass it as a
|
||
|
|
[block argument](../functions.html#block-arguments) to some other method.
|
||
|
|
|
||
|
|
:::dart
|
||
|
|
var fn = new Fn {
|
||
|
|
IO.print("The body")
|
||
|
|
}
|
||
|
|
|
||
|
|
It is a runtime error if `block` is not a function.

||

### **call**(args...)
