	A BlockContext can return a value in two ways. After the bytecodes in the block have been executed, the final value on the stack is returned as the value of the message value or value:. The block can also return a value to the message that invoked the CompiledMethod that created the BlockContext. This is done with the regular return bytecodes. The hypothetical method for Collection ~~containslnstanceOf~~: uses both types of return from a BlockContext.		A BlockContext can return a value in two ways.
