I have not used nim for a while, mostly because my current project is in typescript, now, wouldn't it be easier if I wrote TypeScript?
Case sensitivity helps readability and code maintainability, and If I remember well, nim team always believed that the language should be assisted by a proper editor or IDE. It would be easier to analyse and refactor code with case sensitivity than without. Currently developers are allowed to choose different styles to write variable and function names, without having the compiler complaining about it, and one may argue that this is productive, but in reality, and specially in big projects (that import and borrow code from other code bases) it's not (it's a nightmare), imagine a developer jumping between different code bases and reading the same function called in different styles each time (getData(), get_data(), getdata(), gEtDaTa()) Compilers aren't there only to convert syntax into bytes code, it's in their duties to ensure code validity and consistency, this helps later the next developer trying to extend and maintain the code. Having the compiler enforcing case sensitivity helps improving Nim's readability, and its adoption in big projects, So I'm voting yes for case sensitivity.
