I, unenlightened one, am trying to understand Aliasing Variables.

What is the meaning/purpose of code like 

*z=\$x;

[download]
Is *var called the star sigil? Google doesn't seem to think so. Is this star stuff an artefact of an earlier version of perl? If there are still reasons to use *var with modern perl, where can I learn more about it?

And finally, for a concrete code example, how would I get this to compile without errors under use strict? 

#inspired by http://www.perlmonks.org/index.pl?node_id=98721
use strict;
#use warnings;
my $x=2;
*z=\$x; 
print $z;

[download]
Note: Without use strict, this prints 2.

Thanks for your wisdom!
