it just makes a hash from whatever data is in the @array array. The keys and values will be the same.

CODE
@array = qw(foo bar bash 1 2 3);
@hash{@array} = @array;
foreach $key (keys %hash) {
   print "key = $key, value = $hash{$key}\n";
}

output:

CODE
key = 1, value = 1
key = bar, value = bar
key = bash, value = bash
key = 3, value = 3
key = foo, value = foo
key = 2, value = 2

I haven't used Perl for some time now, but you could print out @hash after using the snippet.
I tried this in python and it didn't work:
TypeError: dict objects are unhashable

Hope this helped a bit.

kuratkull,

did you not see my reply? He can't print @hash anyway, as its a hash that is created, %hash, not an array.
