## Generator functions are convenient ways to create iterators. Whatever the
## return type is will automatically be wrapped in an Iterator. In the following
## example the function return type would become `Iterator<String>`.
##
## Unlike a normal function you use a yield statement which pauses the function
## call until the next element is requested. Return can still be used in a
## generator function, however it will be used to enact a full stop
