If you don't specify the receiver in "self.value = ...", Ruby will
interpret "value = " as meaning that value is a local variable, rather
than a method.  That's how Ruby disambiguates such expressions -- so
if you want it to be a method call, you have to disambiguate it in the
other direction by specifying "self".
