Trying out golang short circuits

short-circuit.go

package main

import "fmt"

func main() {
	// false
	fmt.Println(shortCircuit())
	// panic
	fmt.Println(brokenCircuit())
}

type optional interface {
	Optional() bool
}

func shortCircuit() bool {
	var test interface{}
	opt, ok := test.(optional)

	// Returns early, does not evaluate opt.Optional()
	return false && opt.Optional() && ok
}

func brokenCircuit() bool {
	var test interface{}
	opt, ok := test.(optional)

	// Calls opt.Optional, panics
	return opt.Optional() && false && ok
}
