Subject: array element isset test broken on 5.27.8

A recent bugfix in bleadperl, commit 6661956a23de82b41adc406200054293d6d7aded, which is due to be released in Perl 5.27.8, causes Class-MethodMaker to fail one of its tests. The failing test is for an isset call on an element of an array property. It fails because an earlier call to retrieve the whole array value now has the side effect of causing all array elements to exist. Note that the concept of non-existence of array elements in the array's index range is discouraged. -zefram

That's not the BBC issue. It can't find the XS object because you failed to put the blib directories into @INC, and if that wasn't on your mind then you may also have failed to populate blib by building. -zefram

The tests pass again. I tried perl5.27.8-157-gef80cd9 See also: http://matrix.cpantesters.org/?dist=Class-MethodMaker%202.24;perl=5.27.9;reports=1#sl=7,1
