function in Ternary operator gets executed

[AlexCosteaWK]

The Ternary operator bas a BUG,

in the expression
true ? say('yes) : say('no')
I get BOTH 'yes' and 'no' as an output when I should only get 'yes'

in the expression
false ? say('yes') : say('no')
I get only'no' as expected

Can someone help me with this?

Thank you,
Alex C.

please see attached code for testing

package main

import (
	"fmt"

	"github.com/Knetic/govaluate"
)

func main() {
	funcs := map[string]govaluate.ExpressionFunction{
		"yes": func(args ...interface{}) (interface{}, error) {
			fmt.Println("should execute", args)
			return nil, nil
		},
		"no": func(args ...interface{}) (interface{}, error) {
			fmt.Println("should NOT execute", args)
			return nil, nil
		},
	}

	str := ` [var] == true ? yes('good') : no ('bad')`

	exp, e := govaluate.NewEvaluableExpressionWithFunctions(str, funcs)
	if e != nil {
		fmt.Println(e)
	}

	vars := map[string]interface{}{
		"var": true,
	}

	fmt.Println("----Exec with value is true----")
	exp.Evaluate(vars)

	fmt.Println("----Exec with value is false----")
	vars["var"] = false
	exp.Evaluate(vars)

}

----Exec with value is true----
should execute [good]
should NOT execute [bad]
----Exec with value is false----
should NOT execute [bad]

Program exited.
