Python has never followed the DWIM anti-pattern as a philosophy. DWIM goes against the Zen of Python: "In the face of ambiguity, refuse the temptation to guess." You want Python to guess that something which doesn't start with "def" and doesn't end with a colon is a function definition, rather than a class definition, or a messed up `if func(a, b)` statement, or a messed up `while func(a, b)` statement, or a messed up `with func(a, b)` statement. No thanks. -- Steven D'Aprano “You are deluded if you think software engineers who can't write operating systems or applications without security holes, can write virtualization layers without security holes.” —Theo de Raadt -- https://mail.python.org/mailman/listinfo/python-list
