To be precise - why the ':' after the sort?
'%players.sort' calls the 'sort' method/sub on the hash '%players'.
'{.value}' runs '.value' on $_ at some point. But when?
So once again, what is the ':' doing? How else could this code be
written?
I think I have this right: perl5 has indirect object syntax, which is
ambiguous (the parse of a program can change by whether perl5 had
previously seen a sub by that name).
In perl6, the colon is required to signify an indirect object, even if
there are no following parameters.
