Ha, neat trick. But macro substitution and a purpose-built language are very different — Han has a full pipeline (lexer → parser → AST → interpreter + LLVM codegen) designed around Korean from the ground up.
Error messages, REPL, LSP hover docs are all in Korean. You can't get that from #define 만약 if.
yeah, making a whole language is way more impressive!
anecdotally it is also interesting to use with ai because apparently it is "harder to be on autopilot" based on a huge pre-existing corpus of code when you write it in a different language. could activate different reasoning regions somehow.
(i just appreciate what can be trivially accomplished in c even if it's kind of janky after spending way too much time in the JS preprocessor mines...)
