Title: clear_all returns void (and not the result of inst_clearAll() invocation)

The inst_clearAll method is not returning any value so it does not make sense that clear_all mehod returns the value of inst_clearAll inocartion.

So, I suggest remove the return instruction and change the clear_all method documentation to be cleear that the method returns void
