We try to :-). Specifically, there are designs underway to implement e.g. hyper operators - those things that apply an operator to an array of values, irrespective of order - by SIMD instructions on the hardware level. If you're interested you're very welcome to come and check it out.

[edit] - there is also some progress in speeding up list operations, because as it turns out making all lists lazy is not a really good way to do fast list computations. This is known as the 'Great List Refactor' (GLR) in perl6 circles, and spoken of with awe :-)

Is there a mailing list where such things are discussed?

We don't really use a mailing list, but we do have an IRC channel on freenode: #moarvm. Although just as often MoarVM-specific issues are discussed on #perl6
