-<p>
-  It's possible for a function to have both a Gleam implementation and an
-  external implementation. If there exists an external implementation for the
-  currently compiled-for target then it will be used, otherwise the Gleam
-  implementation is used.

-<p>
-  This may be useful if you have a function that can be implemented in Gleam,
-  but there is an optimised implementation that can be used for one target. For
-  example, the Erlang virtual machine has a built-in list reverse function that
-  is implemented in native code. The code here uses this implementation when
-  running on Erlang, as it is then available.
