Ok, this is a somewhat workable solution. Cons: 1) You have to be more conscientious regarding how many tabs you use at the beginning of a line. If your text editor does not display tabs explicitly (SciTE can), it can be a *REAL* hassle. 2) Because you have to use all pure spaces after the proper # of tabs, you will often end up having to type a lot of them compared to if your tab key generated pure spaces. Pro: 1) Happily, you do get your 'semantic indentation' so people can dynamically change the indentation-size they want to view your code with. You do need everyone to understand 1 thing: NEVER use tab characters (and consequently the tab key) for anything EXCEPT semantic indentation. Big question though: is the above guaranteed to work nicely in all situations in python? Also, in free-format languages like C, Java, C#, the temptation to mix semantic and arbitrary indentation might be just too great for sloppy programmers. If anyone wants to use tabs, I think the above is the ONLY right way to use them and it also happily eliminates any arguments over how many spaces you should use for your tab setting. If ALL tab users followed this convention, I will happily consider myself agnostic... ;-) Now, on to the next holy war... date formats....
