I would also like using tabs for indentation without the `#? replace(sub = "\t", by = " ")` first-line-stunt.
I agree, that mixing tabs and spaces (like Python allows) is bad, but using solely one kind of indentation character in the whole file should be allowed. I don't want to go into a discussion about why two spaces are better than one tab -- I was all for 4 spaces 20 years ago myself when I started learning Python, but despite using this style for several years, I find myself being converted into a one-tab-per-indentation-level guy. So please allow both, just not in the same file.
