Sure, but the glorious thing about Anki is the scheduler -- every time you get a card right it will reschedule reviews further away, on an exponential schedule. And if you self-grade 'easy' then it gets an even bigger time to next review. The cost of throwing in a few syntax oriented cards isn't terribly high in the grand scheme of thing, and there are many other bits of programming languages that are amenable to memorization -- libraries, APIs, common datastructures and idioms.
