// What's the best syntax for this:

// no trailing-closures
// explicit about what's happening, but those ()'s aren't needed... can we do better?

throwActions.filter({ $0.direction == dir }).map({ $0.action() })

// all trailing closures
// weirdly looks like we're mapping the block, rather than the result of filtering throwActions using that block.

// when specify id as the type, you can use NSObject methods.
// when you specify as a custom protocol, you cannot.
// UNLESS you say that your custom protocol includes <NSObject>


#import <Foundation/Foundation.h>

@protocol CustomProtocol // <NSObject> // uncommenting <NSObject> fixes the issue
