gollark: You said easy, not simple.
gollark: Control structures are weird and hard, even I/O requires a bunch of meddling with syscalls, and you have to manually manage registers and stuff.
gollark: It's not EASY, though, to do anything nontrivial in.
gollark: In a sense, isn't everything?
gollark: If you set the average programmer™ some task like, I don't know, "implement fizzbuzz", they will probably find it much easier to use python than assembly.
