The way you're testing this looks a little suspect to me.  First, Perl 
doesn't take more memory every time you use a new variable.  Memory is 
allocated in chunks, so it's hard to predict when the next chunk will be 
grabbed.

Also, memory is not reclaimed from lexical variables when they go out of 
scope.  Perl keeps that memory allocated to $x AFTER it goes out of 
scope as an optimization.  You have to explicitly undef it to prevent 
this.  Now, $x is just a single blessed reference here, but keep it in mind.
