DrScheme is an implementation of Scheme that is very newbie-friendly. It has several limited sub-languages, etc.
So maybe a command line option can be added to Python3 ( - newbie ? :-) ) that just switches on similar warnings, to help newbies (in schools, where there's a teacher that encourages to always use that command line option) avoid some of the most common traps.
