Does Python 3 have the equivalent of LANGUAGE pragmas? That is, as a
GHC user i can add {-# LANGUAGE OLD_STRINGS -#} and my program works
with the new language standard!I think what ruined Perl 6 is that it is still under development! Avoiding breakage is important. But throwing around comparisons to Perl 6 is not going to help move the discussion along!
