%% Introducing the new `apply` pattern match operand.
%% `apply` is used to delegate the handling of a match
%% to some other function including the action to be taken
%% when a successful match happens. The `apply` statement
%% replaces the "-> body" part of a function/case/receive.
%%
%% Simple example:
%% example() ->
%% Pat = fun(A) when is_atom(A) ->
%% {ok, A}
