I know, many people (not me), still want to write their own OSes. No one can stop you, go for it!

I think I should start to program in Python 3.

People still don’t understand these ground rules…

I have seen a rule in Python’s Makefile

-PYTHONPATH=$(DESTDIR)$(LIBDEST)  $(RUNSHARED) \
    $(HOSTPYTHON) -Wi -tt $(DESTDIR)$(LIBDEST)/compileall.py \
    -d $(LIBDEST) -f \
    -x 'bad_coding|badsyntax|site-packages|lib2to3/tests/data' \
    $(DESTDIR)$(LIBDEST)

The dash in front of the command is to let `make` never mind the return value of the command and continue executing the next command.

I think this can be a huge step forward and it could be very risky at the same time, so other language should wait and see how it actually becomes before making any decision.
