I'm trying to write a callback function for SDL_mixer through

Make it a C function, not a D function:
extern (C) void channelDone(int channel)
{
unmuteMusic();
}
and use & to reference the function instead of calling it:
Mix_ChannelFinished(&channelDone);
It should be extern(C) and, ideally, nothrow. The binding
should be enforcing nothrow, but currently doesn't. I'll change
that now.
Why should the binding force nothrow? I don't understand why you
HAVE to not throw exceptions. Is it because of the C -> D aspect?
