Another reason for preferring hyper is that it makes promises about
parallelizability, whereas the zip/each solutions would tend to

Ah, right. Silly me. I got hyper and reduce confused. Thanks!
Gaal pointed out using zip. What would be the difference then between a
hyper-fatarrow an

Reduce operators only turn infix into list operators. What you really
want here is a hyper-fatarrow:
my %h = @k »=>« @v;

Hyper is not [], but >><<. And >>=><< works perfectly in Pugs, and does
exactly what you describe.
[] is for reduction, and is prefix: [+] 1,2,3

You want a zip:
my %h = @k ¥ @v;
my %h = @k Y @v; # ASCII fallback
my %h = zip(@k, @v); # or maybe zip(@k; @v) this week?

Suppose I have two arrays @k and @v and I want to declare and initialize a
hash %h such that %h.keys eqv @k and %h.values eqv @v.
I could use a direct translation of the P5 idiom:
my %h;
[EMAIL PROTECTED] = @v;
But is there an easy way in Perl6 to do it all in one go? Should this work?
my %h
