Usage
a deref( Maybe<a> v )
Arguments
v The value to dereference
Overview
Extract the value from a Prelude.Maybe (3kaya)

A case statemement is generally more appropriate unless it is known that the dereferencing should succeed (for example, using Dict.lookup (3kaya) on a key known to have been added). deref(x) is equivalent to x.val
