I can get the $testBegin::global but I cannot get the $testEnd::global
my question is that
it seems the test package definition location is the key for this issue.
how perl consider the different order ? why perl can call testEnd::show_me() in main but can't see the $testEnd::global in main ?
there is the code :

#!/usr/bin/perl use feature qw/say/; use Data::Dumper; package testBegin { $global = "I'm in the testBegin package global version"; sub show_me { print "$tag: testBegin package $global\n"; } } testBegin::show_me(); print "-"x60; print "\n"; testEnd::show_me(); package testEnd { $global = "I'm in the testEnd package global version"; sub show_me { print "$tag: testEnd package $global\n"; } }

output:
: testBegin package I'm in the testBegin package global version
------------------------------------------------------------
: testEnd package
