For slice expressions, the reason for the syntax was done on purpose for the following reasons:
* It's the same syntax as Go and Python, making it familiar to others who have used those languages
* It allows for partial ranges e.g. `x[:]`, `x[:n]`, `x[i:]`
* Partial ranges with the _two_ range expressions (a..<b and a..=b) look awful and are inconsistent: `x[..<]` `x[..=]`, `x[..<n]` `x[..=n]`, `x[i..<]` `x[i..=]`
* You effectively only ever want Python/Go like semantics with slicing because Odin is a 0-index language
* Ranges in Odin are only allowed in two contexts: `cases` and `for in` loops.
As for C-style for loops, they are not obsolete by any stretch and any one who thinks so in think that the compiler can easily optimize a magical complex iterator without any problem. In languages without C-style for loops, you'll see people try to emulate them regardless with variables and a while loop, not just an iterator.
As for syntax, where does it say "don't use it"? I really don't understand why people state things without evidence.
