The language isn’t perfect but I love working with it, these 8.1 and 8.2 improvements have really made it sweet.
My biggest gripe at the moment is the (very old) behavior of e.g. preg_match() and sort(). You’ve got a small handful of these common functions that operate on their input by reference/in place which is gross. A new version of these would be welcome.
Php is in a very similar situation, the difference is you can't escape javascript so we all to some extent keep up with its developments. People who leave php left it at a certain point and their understanding of its issues is frozen there. It's very predictable and boring honestly.
