Kyle ❤️ 😇 🌤 🍻 🌈

@kyleve: I love that pattern. I used to do `id foo; { …; foo = …; }`, but blocks make it way easier to understand and encapsulate the work.

@kyleve there's a syntax to do this in C that doesn't greater a block, but I never remember it and #prematureoptimizations anyway

@Javi @kyleve this works: NSArray *foo; { NSMutableArray *mutableFoo = … [mutableFoo addObject:…]; foo = [foo copy]; }

@Javi @kyleve I vaguely recall there's an even cleaner way, but I don't know how to google for it ¯\_(ツ)_/¯

@Javi @kyleve (that last line should have been foo = [mutableFoo copy]; but you knew that)

@nicklockwood @Javi Didn’t even notice that :-)

@kyleve @Javi I think this is supposed to work, but doesn't. Maybe its a compiler setting? self.frame = { CGRect r; r.origin = … r; }

@nicklockwood @kyleve @Javi You need parens.

@kyleve You can also do ({…; retVal}) but maybe this is more clear.

@kyleve var = ({ NSObject *obj = http://NSObject.new ; ... obj; }); is more optimized
