Hash creation with duplicate keys

[Ingo Blechschmidt]

Hi,

# Perl 5
my %hash = (a => 1, b => 2, a => 3);
warn $hash{a}; # 3

But I vaguely remember having seen...:

# Perl 6
my %hash = (a => 1, b => 2, a => 3);
say %hash<a>; # 1

Can somebody confirm this?

Yes. This is for the case:

foo(a => 1, *%defaults);

So that foo's $a gets one even if it exists in %defaults.

It's likely that the leftmost-wins rule applies only to binding,
not assignment.
