Function Operator

expr.go:44–55

Operator allows to replace a binary operator with a function.

(operator string, fn ...string)

// Operator allows to replace a binary operator with a function.
func Operator(operator string, fn ...string) Option {
	return func(c *conf.Config) {
		p := &patcher.OperatorOverloading{
			Operator:  operator,
			Overloads: fn,
			Env:       &c.Env,
			Functions: c.Functions,
			NtCache:   &c.NtCache,
		}
		c.Visitors = append(c.Visitors, p)
	}
}

// ConstExpr defines func expression as constant. If all argument to this function is constants,
// then it can be replaced by result of this func call on compile step.
