Add a temporary stubbed method replacing name for the duration of the block. If val_or_callable responds to call, then it returns the result of calling it, otherwise returns the value as-is. If stubbed method yields a block, block_args will be passed along. Cleans up the stub at the end of the block. The method name must exist before stubbing.
