Proof of correctness, or even a graspable notion of correctness for the
whole semantics of the language. If you consider that hygienic macros
(that is, macros that don't make a mess of every concept you have of
"namespace") were introduced quite late, you might get a grasp on how
bravely and hackish they were designed.

Yes, I suppose so, but you'll be left with Haskell with an OOP Syntax,
and a style of OOP that uses Objects mainly as closures, which isn't a
thing OOP coders regularly, or at all, do, to get the granularity of
replacements that is necessary to consider them useful in the first

Some years or decades ahead, perhaps Haskell will not be able to avoid
being successful anymore, and that is the time where you'll see things
that look like Java, feel like Java, work like Java, but still use a
Haskell RTS.
