Hi, no, you think, that my desire is to load the module on a condition, this is not true. I like to enable it on a condition in another scope. For example, this works fine, but I want use bytes only if $Y::VERSION  < 1.

BEGIN {
package Y;
$VERSION = 0.1;
1;
package X;
use bytes;
sub l{ return length shift } 
1;
}
package main;
no bytes;
$x = chr(3456);
print X::l($x);
