Module1::CONSTANT_1() is fully qualified name so it doesn't need

if you import something, you only see the last part of the name
(CONSTANT_1) in your current symbol table. you seem to have cross over
those two concepts.

no, you could have them exported by default so you wouldn't need the
qw// part.

use and require do the same searching in the same dirs. the only
differences are that require is run time vs compile time for use and use
will call the import method on the loaded class. you can't import with

the dirs have nothing do to with this. it is the compile time vs runtime
and importing that matters.

what is wrong with having the users do a use line? make all your
constants export by default (in @EXPORT) and you have a simple
