Yes, or you could combine them into one list:

use lib ('/path/to/1/', '/path/to/2/');
[download]

Each time you do a use lib adds those directories in the list to the @INC array.

that needs to be

use lib ('/path/to/2/', '/path/to/1/');
[download]

To be consistent with the above post of

use lib "/path/to/1/";
use lib "/path/to/2/";
[download]

Full demo:

[davidrw@host davidrw]$ perl -le 'use lib qw(/path/to/1/); use lib qw(
+/path/to/2/); print join " ", @INC[0..1]'
/path/to/2/ /path/to/1/

[davidrw@host davidrw]$ perl -le 'use lib qw(/path/to/1/ /path/to/2/);
+ print join " ", @INC[0..1]'
/path/to/1/ /path/to/2/
[download]

Good point! use lib internally reverses the list passed into the import() function. This allows import() to prepend the entire list onto @INC in the same order as shown on the use lib line. Subtle.
