in reply to What is Exported from modules

If the module uses Exporter and you're not explicitly stating what to import when you use the module, you could do something like:
sub exported_by_default { my ($packagename) = @_; no strict 'refs'; return @{"${packagename}::EXPORT"}; }

untested, by the way.
