But what if I don't want to make every feature in Perl available to scripters in my application? I may not want them to exec, fork or even sprintf. The Safe module provides a means of doing this, but is Perl 6 going to make this task any easier?

A simple subset of Perl mainly for its abilities to provide decision-making to the user is sometimes all the scripting I want in an application. In addition, for "scriptlets" that I want to be executed repetitively, is there a way to tell Perl to compile this once, and execute it multiple times, perhaps with slight changes to variables in its name space? Getting Perl to work efficiently in this situation doesn't seem very easy at the moment. I guess I'm just wondering if Perl 6 will make it any easier.
