I tried Claude Code with a small-ish C++ codebase recently and found it to be quite lacking. It kept making a lot of silly syntax errors and going around in circles. Spent about $20 in credits without it getting anywhere close to being able to solve the task I was trying to guide it through. OTOH, I know a lot of people who swear by it. But they all seem to be Python or Front-end developers.
Do we really know why LLMs seem to score the highest with python related coding tasks? I would think there are equally good examples of javascript/c++/java code to train from but I always see python with the highest scores.
