[ID 20000319.004] Stringify of undef in array; join() or '""'?
Message ID:
200003200226.SAA02975@romana.Tymnet.COM

This is a bug report for perl from jms@romana.tymnet.com,
generated with the help of perlbug 1.27 running under perl v5.6.0.


-----------------------------------------------------------------
[Please enter your report here]

  perl -wle '@_ = (undef,undef); $_ = "@_"'
  Use of uninitialized value in join at -e line 1.
  Use of uninitialized value in join at -e line 1.

Is there a more optimal wording for that warning?
There is no explicit call to join() there, just an
implict call from a non-overloaded stringify of an array.

  Use of uninitialized value in '""' at -e line 1.

[Please do not change anything below this line]
