Windows Media Player Playlist

WPL (Windows Media Player Playlist) is a computer file format that stores multimedia playlists. It is a proprietary file format used in Microsoft Windows Media Player versions 9–12.[1][2] The elements of WPL files are represented in XML format. The top-level element, smil, specifies that the file's elements follow the SMIL (Synchronized Multimedia Integration Language) structure.[3]

gollark: They are "cool", as instead of just returning a function can `yield` to pass some values up to its parent, then get `resume`d.
gollark: Was I unclear? Consider Lua's coroutines.
gollark: Oh, and as all functions are implicitly cooperatively multithreaded coroutines, it is possible for a function to suspend execution and then have the parent edit the locals in it.
gollark: I agree. That's why Macron actually lets you edit the closure-bound variables of functions, and *preemptively* set their locals before they even run.
gollark: Yes it does. Anyway, ICMP(v6) perhaps?
