and use & to reference the function instead of calling it: Mix_ChannelFinished(&channelDone);
To expand on this, D allows functions to be called without parentheses. `channelDone` is actually a function call, whereas in C, it's treated as a function pointer. In D, you have to take the address of a function just as you would any other type, hence `&channelDone`.
