true.

But that's still the BEGIN-in-FIFO/END-in-LIFO that that was being discussed. My point was more to the fact that since this...

package A;
BEGIN { ... $a ... } // A's 0th BEGIN
use B $a;
END   { ... }        // A's 0th END
[download]

...is basically this...

package A;
BEGIN { ... }                      // A's 0th BEGIN
BEGIN { require B; import B $a }   // A's 1st BEGIN
END   { ... }                      // A's 0th END

...you really want to make sure that A's 0th BEGIN block, happens before it's 1st BEGIN block (which so happens to get executed before B's 0th BEGIN block -- if it has one.)
