Using a standalone ‘else’ would tickle my brain in the same nice way that being able to declare a variable inside an ‘if’ statement as if it were a ‘for’ loop (witch you can do in modern C++) does.

Many languages let you scope variables.

In c# you can create an arbitrary scope to declare variables in. Most likely in others as well.

  Ah clever, didn’t think of doing this. Not having to encapsulate if statements in scopes would still look cleaner though

    It’s handy if you’re creating temp variables for single use that you don’t need to use again.
    
    Although I admit I’ve only ever done it a couple times lol
    
    Again in c# you can omit the scope and only the next statement is part of an if or loop.

Or a rust “if let”

  Ooh yes. Rust is king when it comes to this sort of inline stuff. Inline match. Mmmmmm!

Block scoped variables are bad?
