For example, explicit control flow vs. messages.

Oberon's elems framework seems to be a bit in the middle.

Okay, scripting languages are a different area ... you usually
dont have all the memory management issues here, which makes
many things a lot easier for the programmer (with certain costs,
of course)

Yeah, when often have to cope w/ disjunct variants, subclassing
is the natural way to go. But often, the problems are way more
complex, eg. having different aspects and behaviours, which might
even depend on other situations. In those cases, just class trees
arent sufficient anymore - especially if you need efficiency.
