#
# A Ruby method call that returns a hash
# can be substituted for the hash contents.
# For example, Haml::Helpers defines the following method:
#
# def html_attrs(lang = 'en-US')
# {:xmlns => "http://www.w3.org/1999/xhtml", 'xml:lang' => lang, :lang => lang}
# end
#
# This can then be used in Haml, like so:
#
# %html{html_attrs('fr-fr')}
#
# This is compiled to:
#
# <html lang='fr-fr' xml:lang='fr=fr' xmlns='http://www.w3.org/1999/xhtml'>
# </html>
#
# You can use as many such attribute methods as you want
# by separating them with commas,
# like a Ruby argument list.
# All the hashes will me merged together, from left to right.
# For example, if you defined
#
# def hash1
# {:bread => 'white', :filling => 'peanut butter and jelly'}
# end
#
# def hash2
# {:bread => 'whole wheat'}
# end
#
# then
#
# %sandwich{hash1, hash2, :delicious => true}/
#
# would compile to:
#
# <sandwich bread='whole wheat' delicious='true' filling='peanut butter and jelly' />
