The `ListMapFn` functor provides a sorted-list implementation of the
xref:sig-ORD_MAP.adoc[`ORD_MAP`] signature parameterized over the key type.
This implementation is light weight and fast for small domains, but
for larger applications, it is recommended that one use the
xref:fun-RedBlackMapFn.adoc[`RedBlackMapFn`] functor instead.
