Hello monks,

Super Search has failed me. Is there a way to declare a hash and slice-initialize it in one statement, under use strict? I'm guessing it's going to be nasty-looking code if it's even possible, so whether I use it is debatable, but it's one of those "It might be possible, I just can't think how!" kinds of things I've always been curious about.

use strict;

my @keys = (1..3); my @values = (4..6);

my %hash; @hash{@keys} = @values;  # works, but two statements

# my %hash{@keys} = @values;  I wished this worked, but syntax error

# my @hash{@keys} = @values;  Also syntax error

# my $hash{@keys} = @values;  Clearly wrong, and dumb (and syntax erro
+r)

my %hash = map {$keys[$_] => $values[$_]} (0..$#keys); # Far too long-
+winded

no strict; @hash{@keys} = @values; # works, but ew
