Unity Transform extension method to make setting position less painful

TransformEXT.cs

using UnityEngine;

public static class TransformEXT
{
    public static void SetPosition(this Transform transform, float x = float.NaN, float y = float.NaN, float z = float.NaN)
    {
        var pos = transform.position;
        if (!float.IsNaN(x))
            pos.x = x;
        if (!float.IsNaN(y))
            pos.y = y;
        if (!float.IsNaN(z))
            pos.z = z;

        transform.position = pos;
    }
}

Usage Example:
If GameObject.transform.position is 0, 0, 0:

GameObject.transform.SetPosition(5, 10, 4); // pos is now 5, 10, 4
GameObject.transform.SetPosition(5); // pos is now 5, 0, 0
GameObject.transform.SetPosition(x: 5); // pos now 5, 0, 0
GameObject.transform.SetPosition(y: 10); // 0, 10, 0
GameObject.transform.SetPosition(y: 10, z: 4) // pos now 0, 10, 4
