If you pass an array to haml it will join the values with spaces:
%a{:class => ["foo", "bar", "baz"]}
=> <a class="foo bar baz"></a>
If one of the values is nil, it is handled for you.
%a{:class => ["foo", ("bar" if false), "baz"]}
=> <a class="foo baz"></a>
This behavior plus helpers is very useful and doesn't require improvement,
IMO.
