Re^2: ||= in Hash Slice

Yup, I guess that works, but I was hoping for something a bit more elegant.

@{$audit}{@$copy_fields} = map { $item->{$_} || '' } @$copy_fields;

Is probably the nearest I'll get.
P.S. The '' vs. 0 difference is irrelevant here in my case, I just want avoid undefs.

That may not, probably won't, work in all cases ... consider when the value of `$item->{$_}` is `0`: in this case, the wanted value of `0` will be overwritten by the empty string, since `$item->{$_}` is, from a perl POV, false. Hence Corions suggestion, tho' not quite what you were seeking, is better. A user level that continues to overstate my experience :-))	[reply] [d/l] [select]
