How do I skip some return values?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

One way is to treat the return values as a list and index into it:

        $dir = (getpwnam($user))[7];

Another way is to use undef as an element on the left-hand-side:

    ($dev, $ino, undef, undef, $uid, $gid) = stat($file);

[Corion]: LanX: Then the problem should persist without encoding to base64 too ;)
[LanX]: I think it's a flag problem ... I'll produce a reprodocable example for SOPW
[Corion]: "flag problem" to me sounds like "contains UTF-8 bytes but was never properly decoded to an UTF-8 string"
[LanX]: not my code ...
[choroba]: yeah, sounds like one of the strings is not flagged as UTF-8
[choroba]: which usually means its input wasn't handled correctly
[Corion]: choroba: Yeah, I think that would be the good solution
[LanX]: I suspect the first string which comes from the DB ...
[LanX]: ... but this part is already in production for a year now
[Corion]: LanX: The "good" approach here would be to use the appropriate DBI parameters to make the driver decode strings properly. But that will have a ripple-on effect of messing up all the places where manual decoding happens ;)
