* `else` on same line as `if` brace.
* `var` only when the type is shown.
* Removed unnecessarily locals, eg `var events = this.events; var eventsItems = events.Items;`.
* Don't indent `case`.
* ExposedList for EventQueue just so iteration can use array indexing.
* EventQueue, inner members (struct/enum) after methods.
* No braces for single line `if/else/for`.
* Removed comments noting ref impl code, eg `// abc.setSize(xyz);`.
* Removed comments that didn't add to what the code shows, eg `// Pooling`.
* Removed comments not in ref impl about implementation details, eg `// nextTrackLast == -1 ...`.
* Removed commented code we are not using.
* Use local with list.Items when iterating.
