## Object extensions

### `Object#is_one_of?`

Like `is_a?` but multiple types to be checked in one go

    >> "foo".is_one_of?(String, Symbol)
    => true
    >> :foo.is_one_of?(String, Symbol)
    => true
    >> 1.is_one_of?(String, Symbol)
    => false

## Method call extensions

### `Object#_?`

We have the "." operator to call methods on objects. These extensions introduce two "special dots". "`._?.`" only calls the method if the receiver is not `nil`.

    >> "foo"._?.length
    => 3
    >> nil._?.length
    => nil


### `Object#try`

"`.try`" only calls the method if the receiver responds to that method.

    >> "foo".try.length
    => 3
    >> :foo.try.length
    => nil
