If you are using the OOBit, you can also replace the colon with the dot.
method Class.Method (bar)
foo = bar -- assign self.foo = bar
end
or:
Class.Method = method (bar) foo = bar -- assign self.foo = bar end
or even:
Class = {
foo = 10;
Method = method (bar) foo = bar -- assign self.foo = bar end;
}
