Could someone help me understand what is going on in the following snippet?
my %players = {'william'=>2, 'peter'=>3,'john'=>1,'mary'=>5};
my @ranking = %players.sort: { .value };
for @ranking {.say};
I cut and pasted from Patrick's blog on sorting and played around to
get an array.
But ... I dont understand what is being passed to @ranking.
More precisely, I dont understand the meaning of the ':' after '.sort'
Where is this behaviour described? I looked in WITCH under :
but couldnt really understand it :(
