Do you mean at runtime but only once at startup, like parsing a Lua program into bytecode? Or do you mean at true compile time like Zig and Rust format strings?
I hate to be superficial, but languages without braces just feel weird to me. I can use them and have even for a paycheck, but... no thanks. Even Lua, one of my favorite languages (if not #1), always feels at least slightly weird when I use it because of do/end.
Rather, QB was the pico8 of the 1990s. Convenient, self-contained, mysterious, quasi-powerful, in-app help menu for the entire language and API, and a few built-in demo games.
