You're asking for the impossible, or if it is, it's going to be an ugly mess. Sure, it's nice to get a simple result that doesn't use extra variables, but if it becomes unreadible, then you're going to confuse others as to the meaning of your code. In this case, using a temporary hash is not going to increase your memory usage save for maybe an extra byte if you create a reference to the hash, and the code will be much easier to read.

But here's another solution that doesn't use any extra variables beyond $_: 

use Data::Dumper;
my @names = qw ( web email stuff );
my @values = qw( 33 44 55 );
my $ref = { map { $names[$_] => $values[$_] } (0..$#names) };
print Dumper $ref;

(It's still not as clean as using the hash slice, IMO, but if that's what you want...)

It's not what you know, but knowing how to find it if you don't know that's important
