Razorlight: "The helper directive is not supported."

I have @helper abc() {} in my template. When I parse my template with RazorLight, I got this message:

"The helper directive is not supported."

bumped into this today. I found this workaround:

@{
Func<int, int, IHtmlContent> PrintNumbers = (actual, assumed) =>
    new Func<object, IHtmlContent>(@<text>
            @((actual + assumed).EmptyIfZero())
            @if (assumed > 0)
            {
            <span class="--assumed">(@assumed found)</span>
            }
    </text>)(null);
}

and then use it as in good old times:

<td>@PrintNumbers(12,4)</td>

Yes, it's not supported and there is no plan to support it in the nearest future

@toddams Is there any way to work around that? I'm happy to help if a PR is needed

@avs099 Thanks. Perhaps we should add this the FAQ.
