->reduce examples broken?

[pipcet]

• Mojo::Pg version: 4.01
• Perl version: any
• Operating system: any

This is a documentation bug. The POD for Mojo::Pg::Results contains these examples:

say $results->arrays->reduce(sub { $a->[3] + $b->[3] });

say $results->hashes->reduce(sub { $a->{money} + $b->{money} });

which fail to work if there are more than two elements in $results. The proper code for the second example would be:

say $results->hashes->reduce(sub { { money => $a->{money} + $b->{money} } })->{money};

[pipcet]

Alternatively,

say $results->hashes->reduce(sub { $a + $b->{money} }, 0);

That's even shorter than the original code!

Thanks, you are absolutely correct, that was a typo.
