in thread What operator should perl5porters use for safe dereferencing?

I've been using Perl for a while and with Perl's 'do what you want' it would seem that there shouldn't be a new operator. Returning undef seems fine with a warning

    I think it's mostly getting used to the different semantics. I love how much more compact the code is in Objective-C when I don't have to worry about sending messages to undef. But I can equally understand the desire to have that throw an exception. The "I'll add a new operator to provide this" seems like a harder way to have both options - but it does specifically call out "In this case, I am explicitly deciding to do safe deref", so...

    I'l try to get something working so it can at least be tried.
