You don't understand. To fix problems like python3 did, you have to break older code.
Php7 did nothing like that, that's why the "porting" process was so light. But it also means it didn't fix any of the big things.

This is nonsense, PHP 7 contains a long list of backwards-compatibility breaks:

If PHP 7.0 didn't break anything, it would have been called 5.7.
The upgrade is easy simply because these breaks do not have as much of an impact as Python's did.

How would you fix this without breaking most PHP code out there?
How would you fix ==, > and < behaviour without breaking most PHP code out there?
How would you fix Unicode without breaking most PHP code out there?
If PHP fixed things like this, it would be a decent programming language, but it would also break a lot of things. Kinda of like what python3 did, only that it didn't have to break quite so much, since python2 was already pretty decent.
