How about the less glamorous:

my %hash = map { $_ => 1 } @array;

which gets you off the separate declaration of %hash and is more versatile in the long run. Or to make your example a real oneliner:

my %hash = map { $_ => 1 } (1..10);

But i assume that in something real you'd be using an array that existed already.
