What Ruby has that Perl lacks

The following Ruby features are likely to be introduced in Perl 6:

Everything is an object
The concept of modules and classes
The way modules/classes work transparently enables functional programming while retaining the firm object model
Advanced exception mechanism
Transparent Fixnum-Bignum conversion in all numerical operations to enable full precision of any huge integer
Named method parameters
and much more...
