To be fair, you can tell your IDE to just turn tabs into spaces and call it a day, that's an issue for all of 5 minutes.

What you can't do is tell your IDE to interpret camel-case as snake-case if you want (or vice versa), just because this package you really need uses camel-case and you want to use snake-case.

That actually makes whitespace syntax in Nim much better. Can't recall the number of times I copied Python code snippets and had to track down lurking tabs.

You can't mix tabs and spaces in the same file since Python 3, which completely solves this problem without imposing one or the other choice on the users.
