For my current project I'm coding every day in Java, ruby, and JavaScript. I waste a lot of tokens doing what used to be simple google searches for language differences since I mix up things like the null-safe operator ruby vs jscript or what is the continue/break statement in ruby vs java. I think Claude is probably very disappointed in me that the most complicated thing I use it for is refactoring old Java loops to use more modern streams which can be unwritable for a human off the top of your head.
