Coupl'a things: firstly, we can make Perl 6 ops as lightweight as we like.

Second, Ruby uses a giant switch instead of function pointers for their
op despatch loop; Matz says it doesn't make that much difference in
terms of performance.

I don't know if I've mentioned this before, but 
http://www-6.ibm.com/jp/developerworks/linux/001027/ruby_qa.html
was my interview with Matsumoto about his ideas for Perl 6 and his experiences
from Ruby. It's in Japanese, so http://www.excite.co.jp/world/url/ may help.
