You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: pseudo_value.go
    path of file: ./repos/qt/interop
    
    the code of the file until where you have to start completion: package interop

import (
	"encoding/json"

	"github.com/therecipe/qt/core"

	"github.com/therecipe/qt"
)

//TODO: this == nil checks

const PseudoQJSValue__UndefinedValue int64 = 0

type PseudoQJSValue struct{ core.QVariant }

type PseudoQJSValue_ITF interface {
	core.QVariant_ITF
	PseudoQJSValue_PTR() *PseudoQJSValue
}

func NewPseudoQJSValue(i int64) *PseudoQJSValue {
	return new(PseudoQJSVa
    
func NewPseudoQJSValue2(d *core.QVariant) *PseudoQJSValue {
	if d != nil {
		qt.SetFinalizer(d, nil) //there is the need to re-assign the finalizer to the PseudoQJSValue pointer to prevent double freeing the QVariant >>>
		ret := &PseudoQJSValue{*d}
		qt.SetFinalizer(ret, (*PseudoQJSValue).DestroyPseudoQJSValue) //<<< by the finalizer in case it was manually destroyed earlier by the destructor
		return ret
	}
	return &PseudoQJSValue{}
}
