It isn't as concise, as Ruby returns eval errors as exceptions:

     while gets
       begin
         eval $_
       rescue
         puts $!
       end
     end

You might also want to have a look at sample/eval.rb in the
distribution. If you want an interactive way to execute Ruby, you
might also want to check out 'irb'.
