i believe that if you need to access some private module thingys, that
thingys are made private erroneously.

i'm still sure that compiler should forbid such casts. there should be
no way to remove 'const' after it's sticked.

but they will. ;-) you know, "just in case" or "to speedup the things".

btw, i think that default module protection must be "private", not
"public". having module imports as private by default but everything
else as public is confusing.

if you need to tweak something private... well, it's not private
anymore, there must be public API to do that. that API can be version'd
out later (or documented).
