If we try and use parens only for precedence, not arg passing:
$('#contact_form').submit -> validate this
becomes
($ '#contact_form').submit -> validate this
which almost makes sense
So what does $('tr').find('td').fadeOut(300)
become?
(($ 'tr').find 'td').fadeOut 300
is that really better than:
$('tr').find('td').fadeOut 300
