Many times when I've used OO languages I've wished for something like this.
What I've often wanted would be standard method that is called before every
subroutine call. If that method returns false then the method that was
called is not called. A standard set of security information is passed in.
That could get kind of expensive so the security method is only called if
the class is specifically set to use it. Something like this:
class Foo::Bar {
use Class::Security::Method 'checker';
sub checker (%meta) {
if (some_security_check())
{return 1}
return 0;
}
}
