The rho example is interesting, though it doesn't compile in current Rakudo.
"1 2 3 ⍴¨ 10 would natively be written in Perl 6 as 10 »xx« (1,2,3)."
perl6 complains about non-dwimmyness. 10 <<xx>> (1,2,3) gives
(10),(10,10),(10,10,10) , I think that matches the rho example.
Ah, I seem to remember something about which way the arrows point with a
scalar. I'll look it up.
"So let’s implement the APL ⌿ operator which works on the columns of a matrix."
I think that's something that perl6 could do better then APL. From
what I understand, APL has some operators that work on columns and
other similar ones that work on rows, p6 has an opportunity to take
the direction/dimension as an argument. Which is something I'm
thinking about...
Good point. Even infix operators can take adjectives!
Can the same effect be achieved with slices?
