Currently pretty much all Rails helpers call tag or content_tag internally to generate tags.

To integrate Hexp with Rails it's possible to override those two methods, and now helpers return syntax tree objects rather than strings.

The main exception are helpers that generate several tags and then join the result.

What I would love to see (I'd happily make a PR) is that helpers use an internal method (e.g. join_tags) that just delegates to Array#join, but that one can override like tag and content_tag.
