Mne perl -w vyjevilo:

Argument "kam" isn't numeric in subtract at D:\pokluda\perl\diverse\test.pl
line
 6.
Argument "-navig" isn't numeric in subtract at
D:\pokluda\perl\diverse\test.pl l
ine 6.
Use of uninitialized value at D:\pokluda\perl\diverse\test.pl line 6.
navig:

kde line 6 je
    print STDERR "navig: ". $obj->{-navig-up}."\n";
cili chce to $obj->{"-navig-up"}, aby se to nepokusilo odecitat (to funguje)
