Hash context

• Perl 6 has a "hash" context to get the hash form of an object.

• Use %( ) or .hash to force hash context:

my $h = <a apple b banana c cherry>.hash;
my $h = %(<a apple b banana c cherry>);     # same thing

• A List in hash context is smart about creating a Hash:
• Pair objects are converted to hash entries
• Other values are treated in pairs as "key" => value

• String keys are the default for hashes; other objects can be keys.
