I think skills and other things have shown that a good bit of learning can be done on-demand, assuming good programming fundamentals and no surprise behavior. But agreed, having a large corpus at training time is important.

I have seen, given a solid lang spec to a never-before-seen lang, modern models can do a great job of writing code in it. I've done no research on ability to leverage large stdlib/ecosystem this way though.
