| Object Equals(Object obj) |
| Determine whether this object is equal to another object |
| Object IfFalse(Block block) |
| If this object is false, evaluate the block and answer the result of the evaluation; otherwise answer null |
| Object IfFalseIfTrue(Block falseBlock, Block trueBlock) |
| If this object is false, evaluate the first block and answer the result; otherwise evaluate the other block and return the result |
| Object IfTrue(Block block) |
| If this object is true, evaluate the block and answer the result of the evaluation; otherwise answer null |
| Object IfTrueIfFalse(Block trueBlock, Block falseBlock) |
