You can get the effect of block-scoped defers by using a local anonymous
function:
func f(a *A) {
func() {
a.mu.Lock()
defer a.mu.Lock()
do_stuff_with_a_locked(a)
}()
do_stuff_with_a_unlocked(a)
}
Perhaps more convincing:
func f(as []A) {
for _, a := range as {
func() {
a.mu.Lock()
defer a.mu.Unlock()
do_stuff(a)
}()
}
}
