There's no synchronization in this code, so other goroutines reading
A or B w/o said synchronization may observe any values. Stalled,
changing in wrong order, random..., you name it.
But if has nothing to do with defer. The particular code is equal to
var A, B int
func try() {
A = 3
B = 5
}
with the set of problems as the version using defer.
