It's possible, and I don't have any rigorous studies to say otherwise. I will double down on my claim that even local (open weight) models are pretty good at writing code in my pet languages that are certainly not in the training set. Then again, I'm not making wildly esoteric languages, so they'd be pretty familiar to anyone.
How would you be able to tell if it's the lesser amount of training data or the difficulty of the language that's making the difference?
