There was a bug in the example of MI classes
I sent before, although the example worked. This is the error:
function
Account:balance() --> method has the same name as a property
return self.balance
end
It is interesting to see why the
example works anyway. When the an Account object is initialized, a
'balance' property is created in the object which hides the balance()
method, which lives in the class (the object's metatable). The example
works because it calls a derived method and the class holding the
derived method does not have a 'balance' property that would hide it.
Just change the name of the method to getbalance() to make this example
correct. It's a revealing bug, anyway.
