I've only ever heard rumours of people learning foreign languages that way.
AFAIK, people overwhelmingly learn the structure of a foreign language formally. And then practice what they've learnt until it becomes automatic.
This method has not worked well for me, perhaps because my understanding of my own language is mostly intuitive so all the various linguistic terms can feel just as foreign as the language I'm trying to learn.
