JavaScript의 eval()처럼 Go 코드를 어떻게 동적으로 실행할 수 있나요?

import (
    "fmt"

    "go/types"
)

func main() {
    // Create a new package
    pkg := types.NewPackage("mypkg", "github.com/example/mypkg")

    // Create a new scope
    scope := types.NewScope(pkg, nil)

    // Insert constants into the scope
    scope.Insert(types.NewConst("x", types.Int, types.NewInt64(10)))
    scope.Insert(types.NewConst("y", types.Int, types.NewInt64(20)))

    // Evaluate simple expressions
    expr1 := "x * y"
    expr2 := "2 + 2"
    expr3 := "x + 17"
    result1, _ := evaluate(pkg, scope, expr1)
    result2, _ := evaluate(pkg, scope, expr2)
    result3, _ := evaluate(pkg, scope, expr3)

    // Print the results
    fmt.Println(result1, result2, result3)
}

// evaluate takes a package, scope, and expression and evaluates the expression in the provided scope.
func evaluate(pkg *types.Package, scope *types.Scope, expr string) (types.Object, error) {
    // Check the expression
    if expr == "" {
        return nil, fmt.Errorf("empty expression")
    }

    // Parse the expression
    parsed, err := types.ParseExpr(expr)
    if err != nil {
        return nil, err
    }

    // Evaluate the expression
    return pkg.Check(parsed.Pos(), parsed), nil
}
