I'm confused about 'defer'. Not the purpose, the chosen syntax.
func confusing() {
print("1")
defer { print("2") }
print("3")
}
Produces 1,3,2. Trying to describe what is happening here is non-trivial... it
runs line 1, then we put line 2 on a stack, then line three runs, then we pop
the stack... what?! And stepping through it in the debugger... ugh.
Unless I missed something obvious, wouldn't placing "code that always has to
run at the end" actually *at the end* not make more sense? Like this...
func clear() {
print("1")
print("3")
always { print("2") }
}
Not only is the code clearly expressing its intent, the actual execution is
following the source.
