Most languages have completely different idioms though. Sure you can write functions, loops, if statements the same in dozens of different language syntaxes, but that doesn't prove anything. I've seen loads of codebases written completely backwardly, eg when a C++ programmer writes their first Python app or a Java developer writes Javascript - they're just writing the same style in a different language, not writing idiomatical correct code as a Python or JS developer would.
