| In templates expressions that have multiple path components (''foo/bar/baz'') require some extra run-time checks. You can change those expressions to use ''php:'' modifier (e.g. ''php:foo.bar['baz']''), which is a little bit faster. | In templates expressions that have multiple path components (''foo/bar/baz'') require some extra run-time checks.
