nice 👍

But also you need to realize #html helper too. Because you will have a problems with following code now too.

def two_spans_in_div
  html.div do
    span 'hello'
    html.span 'world'
  end
end

@davydovanton What's the point of using nested html calls?

[davydovanton]

My hypothesis is that perhaps we'll have a problems with helpers based on html helper inside html block.
But now I see that all tests is passed.
