Title: give the user a way to disable perl5 warnings (only one so far)

when writing

no warnings :p5;

you can get rid of the warning that numbers starting with 0 are not parsed as octals.

I'd like to get some feedback; Especially what else to change. Maybe I should have a look at the P6Regex grammar/actions for more things?
