Reply to Andrei,
IMHO it is better to keep system-fu at the module level instead of
sprinkled all over. This is exactly a case when, counter-intuitively,
more restrictive is better. This restrictions will help people
organize code with few low-level modules supporting a large number of
safe modules, instead of fostering insertion of inline unsafe things
whenever it seems fit.

That's reasonable. OTOH it could end in the "Make it all public" syndrome
if someone just gets tired of excising the really unsafe parts. I think a
'try the current thing and see what happens' approach will be best, for now.
