Dear Monks,

I just wrote a small script:
#! /usr/bin/perl

@a = &test() ;
if ( defined @a) {
    print "defined\n" ;
}


sub test {
    return undef ;
}

[download]
Guess what, it prints defined!!
Of course this is not what I want. What I would like to know is why this happens and how to solve this ?

Thanks a LOT in advance
Luca
