get
retrieves a value by key
Usage:
(get seq key default?)
Returns the value within a sequence that is associated with the specified key. If the key does not exist within the sequence, then either the default value is returned, or an error is raised.
An Example
(define robert {:name "Bob" :age 45})
(get robert :address "wrong")
This example returns “wrong” because the object doesn’t contain an :address property.
