NSMutableSet#merge fails

[kourge@…]

NSMutableSet#merge succeeds if called with another NSMutableSet, but it fails when passed an Enumerable, such as NSMutableArray.

~ kourge$ irb
>> s = Set[1, 2]
NameError: uninitialized constant Set
	from (irb):1
>> require 'set'
=> true
>> s = Set[1, 2]
=> #<Set: {1, 2}>
>> s.merge [3, 4]
=> #<Set: {1, 2, 3, 4}>
>> quit
~ kourge$ macirb
>> s = Set[1, 2]
=> #<NSMutableSet:0x800754380>
>> s.merge [3, 4]

Looks like I’m not properly coercing to a set.

While fixing this I found out that the tests hang in #==…I’ll write a new one about that.

Fixed in [1401].
