Sorry,
liverpole, looks like I totally sent you down the wrong alley.
It's not about undefined values or using strict.
If you leave out the my in my post, it makes better sense. What I wanted to say is that
($ret) ||= foo();
is different than
($ret) = $ret || foo();
regarding
context.
Regardless if $ret is defined or not, foo() is in scalar context in the first statement and in list context in the second.
I've removed the my from the original post to make the intention clearer.
