title: Print a variable to console in Haml to debug Rspec
body: <p>Just landed on a Rails 3 app that uses haml. I am running Rspec tests and trying to print a value of a variable to console. On erb or in a any .rb file, you simply do:</p>
  
  <p>p my_variable.inspect 
  or even string interpolation:</p>
  
  <p>p "this is my variable #{my_variable}"
  So when I run my Rspec tests I get a nice printout on the console evaluating my variables. So now, how you do that in Haml?</p>
