what on earth did you just say?.....
the act of typing teaches nothing.
it's the act of changing variables that makes you learn. eg making a loop run 20 times instead of 10.
memorizing syntax is the only reason for shorter syntax when learning.
memorizing syntax is an alternative to copy/pasting. like you JUST said, copypasta is NOT learning.
i've done lab TA duties before, trust me, everyone copy/pastes and there is nothing wrong with that for the above reasons.
