fun_land v0.7.3 FunLand.Builtin.Map
Maps are Mappable, because we can map over {k, v}
-tuples to create new values.
Maps are however not Appliable, as there is no clearly
Maps are not Applicative, as there is no way to put ‘a value’ inside a map (we don’t know what key to associate it with)
so we cannot define an implementation of wrap/2
.
Maps are Combinable, as we can take two key-value pairs, and combine them.
It is also possible to create a neutral
element: an empty map.
Summary
Functions
A variant of reduce/3 that accepts anything that is Combinable as second argument. This Combinable will determine what the neutral value and the combining operation will be
Callback implementation for FunLand.Reducable.reduce/3
Converts the reducable into a list, by building up a list from all elements, and in the end reversing it

.
Converts the reducable into a list, by building up a list from all elements, and in the end reversing it.
This is an automatic function implementation, made possible because Elixir.FunLand.Builtin.Map
implements the FunLand.Reducable
behaviour.
