Using(IDisposable) will become invalid IL after burst

using scope like this will generate invalid IL code.

    public struct SomeDisposable : IDisposable
    {
        public void Dispose()
        {
            //Dispose something
        }
    }
    [BurstCompile]
    public unsafe struct SomeJob : IJob
    {
        public void Execute()
        {
            using(var handle=new SomeDisposable())
            {
                //Do something
            }
        }
    }

It should be caused by boxing “SomeDisposable” to IDisposable. But console output did not pin where the invalid IL code is from. And as far as I know, no Document has mentioned this case. So be noted.
This should at least be mentioned in doc. Or maybe burst can avoid this boxing behavior when compiling.

I’ll take a note to update the docs - but the above using causes a try block to be generated in the IL and that’s why you get the error.
