Random thought: do you have a feel for how much method dispatch via the byte-code interpreter has an effect on overall performance?

Perl5 and CPython use several C function calls and a hash lookup.  Apple/GNU Objective-C uses a C function call and sparse arrays.  David Stes' Objective-C (POC) uses an inline cache with a fallback to a C function and a sparse array.  C++ uses a single-instruction indirect-jump through a static vtable.

I came up with a technique for building a dynamic, single-instruction indirect-jump vtable and I’m wondering if it’s still relevant.

Hello to everyone coming here from Sam Ruby’s talk! Well, we had the test cases working last night and suddenly today they all fail because the entire python_group got disabled in the parrot source tree. Sigh :/ Anyway, if you weren’t there, you...

Any chance you could use your pull with O’Reilly to get them to have a conference east of the Rockies any time soon?

Ken: no.  As I said, my focus was more on language compatibility.

Christian: here you go, though it looks like I may have overshot slightly.  Oops!

Overachiever. ;)

was hugely sorry to miss Sam’s session...

Another notable in the audience: Rasmus Lerdorf.

So you had the creators of PHP, Perl, and Python in attendance at your session — I wonder how many other speakers can claim that level of interest :)
