state (added in Perl 5.10) can be really nice. Reference aliasing (added in Perl 5.22) is also awesome, but seems too new to rely on. In quick mock-ups, I often find myself using package Foo::Bar { ... } syntax (added in Perl 5.14) but that's trivial to replace with { package Foo::Bar; ... } before distributing the code.
