I couldn’t discern a point either. Having been a smalltalk programmer the only thing I really miss is the exceptions and the way they could be intercepted and a value injected back into the execution flow.
I’m sure we could code up a class browser for any language that offers introspection like C# but I don’t see the point any more when programming has reverted to functional styles or chunks of lambda expressions.
>lambda expressions
smalltalk blocks do this better
