I get the error: (ActiveRecord::Base).create> is not a symbol
calling:
  assert_required_fields User.method(:create), :create, :email, 
:lastname, :password

the code in my library uses send, not call

Of course, I could just change the definition of assert_required_fields, 
but since it is part of a plugin 
(http://topfunky.net/svn/plugins/topfunky_power_tools/lib/topfunky/test_helper.rb 
), I figure there must be some standard way to call it

Thanks for your help,
Sarah
