No, you can call (or use the constant) it without full qualifying it doens't
mean the function or the constant is in your namespace. as you said below,
Perl has way of finding it from the Exporter interface. the function or
constant still belongs to the package it's defined. when you import
something, it only makes it available for you to use in your script. you
don't need to fully qualify it because you said you are an
Exporter(@ISA=qw(Exporter)). I don't use Exporter so I fully qualify it.
how about a little experiment?
#!/usr/bin/perl -w
use strict;
use THGTest qw(HI); #-- See I learn not to use Test :-) Thanks!
print "$_: $::{$_}\n" for(keys %::);
#--
#-- Now do this:
#--
print "$_: $THGTest::{$_}\n" for(keys %THGTest::);
__END__
for the first for(...):
see if you can find HI anywhere. You won't find it because it's not there!
You still can use it but it doesn't belong to you.
for the second for(...):
you will see something like:
HI: *Model::HI
btw, @ISA=qw(Exporter) is not strictly neccessary but pretty much everyone
agree it's a good thing to do for the reason mentioned above...
