NAME

OrderedHash - A hash that you specify the possible keys and theirs order

SYNOPSIS

use OrderedHash;

say %oh1.kv;                                        # (a 1 b 2 c 3)
say %oh1.pairs;                                     # (a => 1 b => 2 c => 3)

my %oh2 does OrderedHash[Int] = b => 2, a => 1;

my %oh4 does OrderedHash[Str, :keys<c b a>] = b => "b", c => "a", a => "c";
