in reply to Is Taint just another property?

Are you referring to something like this? It's experimental now, but attributes will figure quite heavily in Perl 6.

    Yes. is constant is an attribute in Perl 6, and I'm wondering how many things attributes could subsume (not that Perl 6 will necessarily implement them that way). Tainting and the (currently inaccessible) byte/char orientation of a string come to mind.
