it's called "hash slice"! see perldata#Slices

assign a list of same length

  DB<156> @array=1..5
 => (1, 2, 3, 4, 5)

  DB<157> @hash{@array} = ('my val') x @array
 => ("my val", "my val", "my val", "my val", "my val")

  DB<158> \%hash
 => { 1 => "my val", 2 => "my val", 3 => "my val", 4 => "my val", 5 =>
+ "my val" }

UPDATE

for completeness TIMTOWTDI:

$hash{$_}="my val" for @array

has less of a memory footprint.

and

my %hash = map { $_ => "my val" } @array;

is DRYer and makes sure the whole hash is reinitiated.
