Stewart Gordon:
But one possible design for languages like these is to allow indentation to be either entirely spaces or entirely tabs, but not a mixture. This would also be a good way for linters for a variety of languages to behave.
Among the arguments of the Python2.6 interpreter there is also:-t : issue warnings about inconsistent tab usage (-tt: issue errors)
"inconsistent tab usage" means mixing tabs and spaces. Bye, bearophile
