Jaikoo Symbol shortcut

Symbol shortcut

I just found this out today which is pretty sweet. Sometimes I need a symbol but compose it using a string and then call to_sym on that. Turns out there’s a shorter more concise way of doing this:

   @ivar2 = "_two" 
   :"my_string#{@ivar2}"

This returns a symbol :my_string_two. Pretty cool I thought.
