in thread printing every 2nd entry in a list backwards

I don't have time now to test how fast it is, but these are two idiomatic ways of doing in Perl 6, both using a pointy block with two loop variables (only one of which is actually used).

With the range operator and reverse:

for (1..10).reverse -> $x, $y { say $y}
And using the sequence operator which can build a reversed list:
for 10...1 -> $x, $y {say $y }

[Corion]: Hmm - I think I'm not really making friends at $work. "We" (as in $current_project) should enter some Changes into the system, and I just told the Transition Manager, who should do that or tell somebody to do that to learn the system in which they ...
[Corion]: ... should create that Change.
[Corion]: The nicer approach maybe would have been to indirectly tell them that, or tell them who could teach them...
[erix]: No More Mr Nice Guy !
