Slices are your friend!

Notice for this to work with 'use strict' (and you wouldn't *dare* not use 'use strict', would you?), you can't declare AND initialize the hash in the same statement.

And for those of you that wonder what happens if the length of @a is unequal to that of @b (which was me, up until a few minutes ago), if @a is longer, the values that exist at positions greater than the length of @b will be inserted into hash as keys, and the value set to undefined. If @b is longer than @a, values that exist at positions greater than the length of @a are discarded/ignored. 
#!/usr/local/bin/perl -w
 
use strict;
use Data::Dumper;
 
{
   my @a = qw(one two three four);
   my @b = qw(1 2 3 4);
 
   my %hash = ();
 
   @hash {@a} = @b;
 
   print Dumper ([\%hash]);
}
