So you’re expecting developers will upgrade to PHP7 and leave their code exactly as-is? But we shouldn’t fix this conflict b/c it caters to newbie developers?
I mean, PHP7 is a major release; while I don’t know for sure, I’m extremely doubtful the only change you’ll have to make to your code to make it work with PHP7 is changing your constructors. If this is one of several BC-breaking improvements to PHP, I really don’t see why this is an issue.
