How do you comment out html mixed with ruby code?

```
some text <% ... %> more text <%= ... %>
something else
<% ... %>

```

In jsp it's real simple: `<%-- ... --%>`, but I'm unable to find any concise option in rails.

Simple html comments `<!-- ... -->` do not work: ruby code is still executed and yells errors. 

There's an option to use `if false` with html comments, but it's quite verbose, not to mention IDEs doesn't support it.

There's also an option coming from pure ruby, which surprisingly works.

```
<%
=begin %>
... html and ruby code goes here
<%
=end %>

```

It's generally fine, except that it's verbose, weird-looking and none of ruby IDEs I know support it (yep, I like to comment/comment-out with one keystroke).

I'm curious, is there any 'official' of doing this in rails?

Thanks!
