Right? Whether or not it's practical, it's the way we learn.

I used to see that sort of haughty "well why do you want to do X" response all the time on stackoverflow/its ilk (I've basically deprioritized results from that entire network of sites now), which isn't even a good tack as there are plenty of others who might want to do X for other, valid reasons; "why" shouldn't even be a question as far as learning goes.
