Still no:

BEGIN {
    &Internals::SvREADONLY(\undef, 0);
    ${ \undef } = 42;
 &Internals::SvREADONLY(\undef, 1);
}

my $x = undef;

print( ((undef) ? 'True' : 'False'), $/);
print( ((defined undef) ? 'True' : 'False'), $/);
print( (($x) ? 'True' : 'False'), $/);
print( ((defined $x) ? 'True' : 'False'), $/);
print $x;

__OUTPUT__
True
True
False
False
