/*
	Hack to enable the use of block ivars as IBAction targets. Stuffs a bunch
	of nastiness in NSObject, but transparenty works for classes implemeting
	actions: create a property of type BlockAction, assign a block to it,
	and use the property name (with a trailing colon) as the target selector.
	
	Did I mention it's a hack? There are two major problems:
	* Type safety. It assumes any block property will have the correct
	  signature. Can be partially worked around when compiling with Clang,
	  which embeds @encode() strings into blocks, but this is undocumented.

// Sketch for multiple return values in Objective-C

// Method declaration:
- (id, NSError *) someMethod:param;

// Desugars to:
typedef struct { id a, NSError *b } __someMethodResult; // Obviously gensym/anonymous in real implementation
- (__someMethodResult) someMethod:param;

// Return type encoding would be "{?=@@}", anonymous struct of two objects.
