Yes, and that's an alternative that's been proposed (by me and independently by others). The consensus is that it could be done using autobox
. That's my personal preference, with the option to turn off a warning for it:
$z = $not_defined->arbitrarymethod()
Method not called at ...
I personally think that's preferable to a whole new operator; the idea is to make it work in much the same way that sending messages to nil does in Objective-C: it does nothing, and returns nil (which equivalences to 0 in numeric context). For Perl, it'd do nothing and return undef (in list context it'd return an empty list).
