in thread Returned value from subroutine is 1 when returning ""

Oh I understand now. I seem to have misunderstood the ||.

I read the code as (my $o = mysub()) || print ...

I see now that the grouping is my $o = (mysub() || print ...

Thank you.

    When in doubt about what exactly the precedence will be, B::Deparse is your friend. 

    $ perl -MO=Deparse,-b,-p -e 'my $o = mysub() || print STDERR "WHY U NO
+ WORK\n";' 
(my $o = (mysub() || print(STDERR "didnt work\n")));
