Proc Objects

• a Proc is analogous to an anonymous subroutine in Perl
• they're closures meaning they carry context around with them
• Example

  • class AnotherNameSpace #this class knows nothing about the foo variable
      def AnotherNameSpace.call_it(procObj)
        procObj.call
      end
    end
    foo = "a foo string"
    myProc = proc { puts foo }
    AnotherNameSpace.call_it(myProc) #prints 'a foo string'
