in reply to From Perl 5.10 to Perl 6

Depends on your code.

Some 5.10 capabilities don't exist in 5.8, for example, so if you use them and your host is still at 5.8, they won't work. (For details, read the relevant perldeltas).

As for Perl 6: we can listen tonight to a weather forecast for tomorrow... but we won't know if the weather-guessers got it right until tomorrow.

As to your specific "things" -- those wise in the plans for 6. can surely tell you yes or no, but "things like" (emphasis supplied) is too vague to let you even hope for any more than a forecast.
