Oooh, something I sorta understand :).

Try this:

 #!perl -w
 use strict;
 my($x) = 1;


It's all in the scope :). strict is very strict, and it tries to prevent
you from stepping on your own toes. my() creates a variable with local
scope, so it doesn't collide with others.

An alternate:

 #!perl -w
 use strict;
 $main::x = 1;

Now the scope of $x is bound to the "main" package, the implicit
package  for globals and such.

Hope that is mostly correct. We learn best by teaching.
