Currently ;-)

I'll see whether commuting arguments is sufficient enough an incentive to
switch modes: but what concerns the problem with HOFs, there should really
be a solution - at least what concerns the standard library.

I agree: "open" is potentially dangerous. It is not only confusing at
times, it can even break modules (e.g. if you add functions to one module
which shadow definitions in another module).

Best regards,
