Although this seems like an excellent idea, I think we still want to allow
the player to skip a Source which is supposed to loop forever. If we would
use the idea of an iterator, one could create it this way:
from itertools import chain, repeat
intro = pyglet.resource.media("intro.mp3")
main_theme = pyglet.resource.media("main_theme.mp3")
ending = pyglet.resource.media("ending.mp3")
my_playlist = chain(intro, repeat(main_theme), ending)
player.queue(my_playlist)
The idea is that the intro plays once, then the main_theme loops over until
player.next_source() is called. But if this just takes the next element in
the my_playlist iterator, we will never reach the ending song as the
repeat(main_theme) will provide an infinite amount of sources.
If I think about a Media Player, the usual functionalities are : play once,
repeat one song, repeat the whole playlist. So I think this is what we
should try to implement. I guess that the current behaviour of discarding a
Source once it is played is actually surprising to the user. I would then
make this an option, but not the default.
I will make some tests and see if memory-wise it's not too hungry.
