the statement:
print HI;
won't work. it's:
print Test::HI,\n;
that i have in the code. Otherwise, Perl thinks that you want to print $_ to
the HI file

no. sorry! :-(
in that case, Perl probably thinks that you want to call the function HI and
than print whatever that function return to STDOUT.
no such HI function so Perl will panic! :-)

Huh? I thought constants were implemented as functions? In other words, HI

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
in clarifying the issue.
