            Description

            The use of exceptions here https://github.com/puppetlabs/puppet/blob/master/lib/puppet/parser/scope.rb#L530-L543 when running in :warning mode (the default) is slow on JRuby. With a single undefined variable referenced in my hiera hierarchy I found handling this without exceptions resulted in a 20% runtime improvement.

            I suspect both the throw and the exceptions are unnecessary.
