What information is available about a Boolean?

A Boolean type has the following members:

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)

If this object is true, evaluate the first block and answer the result; otherwise evaluate the other block and return the result

Answer the logical reverse of this boolean (true for false; false for true)
