I always liked Pascal's BEGIN and END statements instead of curly braces. There is also Basic where the blocks built into control flow statements, like FOR I=1 TO 5 [code here] NEXT I

I'd argue a lot of programming language evolution is influenced by the capabilities of our IDEs. When you code in a text editor, the terse syntax of C is great and brings advantages over the verbosity of Pascal, Basic or god forbid Cobol. Once your editor does auto-indentation the braces seem redundant and you get Python. Smart completions from IntelliSense are essential to efficiently writing C#, and now that LSP has brought that to every IDE or smart text editor we have the explosion of popularity of more explicit and more powerful type systems (Typescript, typed Python, Rust). Programming languages are shaped by their environment, but the successful ones far outlive the environment that shaped them.
