## Object extensions

### `Object#is_a?`

Extended to allow multiple types to be checked in one go

    >> "foo".is_a?(String, Symbol)
    => true
    >> :foo.is_a?(String, Symbol)
    => true
    >> 1.is_a?(String, Symbol)
    => false
    
Still works the old way

    >> "foo".is_a?(String)
    => true
    >> :foo.is_a?(String)
    => 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
