const is a nice way to make sure that your data will not be modified.
it needs some time to adjust your head to the fact that "const is const
all way down to the bytes", but then it's nice.

yet i still missing c++-like const, which will not try to eat
everything underneath. i.e. a way to tell compiler "this field cannot
be modified, but the data it points to can be changed". this will let
me to get rid of annoying getters.
