I'm not an expert in LLMs, but I don't think character length matters. Text is deterministically tokenized into byte sequences before being fed as context to the LLM, so in theory `mySuperLongVariableName` uses the same number of tokens as `a`. Happy to be corrected here.

You're more likely to save tokens in the architecture than the language. A clean, extensible architecture will communicate intent more clearly, require fewer searches through the codebase, and take up less of the context window.

Go is one of the most verbose mainstream programming languages, so that's a pretty terrible example.

I would be very interested in this research... I'm trying to write a language that is simple and concise like Python, but fast and statically typed. My gutfeeling is that more concise than Python (J, K, or some code golfing language) is bad for readability, but so is the verbosity of Rust, Zig, Java.
