This seems pretty convenient and intuitive. At least, it is possible
to mimic that behavior in Raku:
List.^find_method('split').wrap: { $^a.map: *.split($^b) }
List.^find_method('sin').wrap: *.map: *.sin;
my @words = <a,b c,d>;
my @nums = 0, π/2, 3 * π/2;
say @words.split(',');
say @nums.sin;
gives us
((a b) (c d))
(0 1 -1)
