<h1>Multi-Line Blocks</h1>

<p>
    It would be great to support multi-line blocks.
    Here are some use cases:
</p>

<%
    # Documentation via multiple lines of single-line comments.
    # Like so.
%>

<%
    # view logic that belongs together in a group.
    # e.g. constants:
    FOO = 'foo'
    BAR = 'bar'
    BAZ = 'baz'
%>

<%
    # helper functions that really want to be multiple lines,
    # e.g. for readability or inline code comments:

    # make phrase suitable for use as id/class attribute
    idify = (phrase) ->
        phrase.toLowerCase()
            .replace(/\s/g, '-')    # replace whitespace w/ dashes
            .replace(/[',?]/g, '')  # strip punctuation
%>

<%
    # or to comment out an entire block of HTML.
    # this is better than <!-- ... --> both because it takes precedence
    # but also because the commented HTML won't get sent to the client,
    # which is good for perf but can also be useful for security,
    # e.g. to put a FIXME for an XSS vulnerability. ;)
%>

<p>
    I don't want this HTML to show up in my output.
