in reply to Re: :lvalue, How I Hate Thee
in thread :lvalue, How I Hate Thee

Didn't work, as in $self->{VALUE} maintained it's original value of 'Yes', instead of being set to undef.

What version ot perl was that under?

    5.8.4, but I think you're right that there is something else involved here.

    #! perl -slw use strict; package thing; sub new { bless { VALUE => 'YES' }, $_[0]; } sub value :lvalue { my $this = shift; $this->{VALUE}; } package main; print $]; my $thing = thing->new; print $thing->value; $thing->value = undef; print $thing->value; __END__ P:\test>junk2 5.008004 YES Use of uninitialized value in print at P:\test\junk2.pl line 22.

    Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
    Lingua non convalesco, consenesco et abolesco. -- Rule 1 has a caveat! -- Who broke the cabal?
    "Science is about questioning the status quo. Questioning authority".
    The "good enough" maybe good enough for the now, and perfection maybe unobtainable, but that should not preclude us from striving for perfection, when time, circumstance or desire allow.
      Worked fine for me in 5.8.2:

      5.008002
      YES
      Use of uninitialized value in print at undeftest.pl line 22.
