title: Capistrano upload fails with incorrect arguments error?
body: <p>I'm running </p>
  
  <pre><code>upload('bin/rvm_install.sh','~/rvm_install.sh')
  </code></pre>
  
  <p>in my Capistrano deploy script. And it's spitting out the following error:</p>
  
  <pre><code>capistrano-2.14.2/lib/capistrano/configuration/namespaces.rb:110:in `block in define_task': wrong number of arguments (2 for 0) (ArgumentError)
  </code></pre>
  
  <p>Why is this happening?</p>
