Reversed operators will reverse the meaning of the two operands.
So instead of switching the two arguments as in $b cmp $a
one can write $a Rcmp $b.
It is not yet implemented in Rakudo and frankly I don't yet see
any use of it but I am sure others will.
I wonder if the same would also work on operators such as gt ?
Could I use $x Rgt $y meaning $y gt $x ? Why is that good?

#!/usr/bin/env perl6
use v6;
# spaceship operator
say 1 <=> 2; # -1
say 2 <=> 1; # 1
say 1 R<=> 2; # 1
say 2 R<=> 1; # -1
