| Subject: | IO::Socket::UNIX/INET double importation |
While I was playing around with POE, I enabled Exporter's verbosity ( $Exporter::Verbose = 1 }
And noticed that your IO::Socket::INET/UNIX module does a double importation of ALL the constants in Socket.pm
I investigated, and found out that lines 11 and 12 of IO::Socket::INET is:
use IO::Socket;
use Socket;
IO::Socket seems to be simply a wrapper around Socket, hence exporting Socket's symbols twice in the following excerpt:
