Is there a way to include several library paths with
use lib
at once, so that I can do something like

use lib $ENV;

The following seems not to work ...

@array = split(/ /$ENV);
foreach $array_item (@array){
use lib $array_item;
}

Try:

unshift @INC, qw(/some/path /some/other/path);

You may want to put this into a BEGIN block:

BEGIN {
...
}

See perldoc lib.

See perldoc -f split.


I doubt that

use lib split(' ', $ENV) ;

will work, because the separator is likely ':', and there may be empty
list members.

I export the PERL_LIBRARY_PATHS environment variable by myself, so that I
can have the paths separated by whatever I like. But it doesn't work
anyway.

However I found out that

BEGIN { use lib split(':', $ENV); }

works.

As would

BEGIN { BEGIN { use lib split(':', $ENV); } }

or

BEGIN { BEGIN { BEGIN { use lib split(':', $ENV); } } }

or simply

use lib split(':', $ENV);
