lazyness implies eta equivalence :
(fun x -> f x) is not observationally equivalent to f in a strict
language.
I don't think this is a major problem of strict language over lazy ones
... Especially
compared to the problem of complexity prediction which is harder in lazy
languages ...
And by the way : PML is strict, pure with exceptions ... And I consider
exceptions to be pure because they enjoy reference transparency ... But
the PML compiler is not yet there ...
Cheers,
Christophe
