Are Objective-C blocks autoreleased?

Solution
Yes, you need to copy. Not because they are autoreleased, but because they start on the stack. Note that blocks also behave like regular Objective-C objects, so that you can copy them using the regular `copy` message:
void storeBlockForLater: (dispatch_block_t) block
{
[someArray addObject:[[block copy] autorelease]];
}
Or, if you have a block property:
@property(copy) dispatch_block_t block;
Retaining does not help here.
Problem
If I declare a block like this `^{ DoSomething; }` and put it in an instance variable, do I need to `Block_copy()` if I'm going to keep it around?
