Bug #20289 for Tie-Hash-MultiValue: assigning multiple values at once fails

Subject:

assigning multiple values at once fails

The documentation says that assigning multiple values at a time should work, i.e. : $hash{'more'} = ('fee','fie', 'foe', 'fum'); Unfortunately this only assigns the last element to the list: x \%hash 0 HASH(0x359970) 'more' => ARRAY(0x3599f4) 0 'fum'

You are correct; at the moment I don't see a (non-filter) way to emulate list assignment. I would suggest a 'foreach' instead: foreach my $item (qw(fee fie foe fum)) { $hash{more} = $item } Not as nice, but it's the best alternative that I can come up with that doesn't involve nasty stuff. I will fix the docs in the next release.

Docs have been updated with an example of how to add multiple values at once via map(). Sorry I wasn't able to supply a more transparent solution.
