What I like about the Lingo model is the simplicity that every object is a
clear 'thing' that can be seen and inspected. There's a certain elegance
to
the ECMA system where *everything* is an object, but you lose the sense of
distinction between objects, properties and methods that you have in
Lingo.
Using this particular issue as an example, what exactly *is* 'super'? It's
not an object in the same sense that our instantiated class is, it's a
kind
of hidden layer of the class.
I'm not saying one system is better or the other (I started with Lingo, so
I'm more comfortable with it, but I like both).
Think of 'Super' as opening a Russian Doll. When you call a given method,
it's at the current outermost level. When you use Super you remove a layer
and work with what is nested inside.
I don't know if that helps or not.
I don't know lingo, but Flash behaves more or less as most OO languages do.
