You don't need to enclose each argument in brackets, you just need to
enclose all arguments in brackets (which is the recommended practice).

start_form_tag(
	{:action => 'blah'},
	{:class => 'css1'})

works fine.

Subject: Passing inline hashes

I just stumbled across an intresting problem with passing two hashes to
a method -- I was trying to pass inline hashes and ruby interpretted
them as blocks.  (Makes sense looking back).

start_form_tag :action => 'blah', :class => 'css1'

This call was putting both values into the first parameter of the method
(a hash), and none in the second one.  So I altered it:

start_form_tag {:action => 'blah'}, {:class => 'css1'}

Which of course ruby thinks the {} are blocks and pukes.

To explicitly tell ruby they are hashes, I had to wrap them with ().

start_form_tag ({:action => 'blah'}), ({:class => 'css1'})

Which seems awkward, as most languages use the {} syntax for inline
hashes.
