That doesn't sound useful, at all.

For example:

	sub foo {
	   my($x, $y) = @_;
	   bar(2*$x, $x+$y);
	   print $x, $y;
	}
	sub bar {
	    ...
	    continuation; # stop and restore to this point;
	    ...
	}

When bar returns, the values of $x and $y will simply be lost.

I can live with files that all have been closed, database connections
that have been lost, etc. But *all* variables reset, global and lexical?
You'll get a pretty useless system, then.
