The MINOR functionality of "this" is an improvement at times, but more often than not it isn't a sufficient change to warrant the PAINFULLY CRYPTIC and often outright vague syntax.
In that way it's not an improvement, it's a bunch of people screaming "wah wah, eye dunz wunnu type a hole wurd!".
Though it could just be my programming background gives me a very different opinion of C syntax languages and what constitutes cryptic and obfuscated code. I spent a decade working in Ada... it gives you a very different perspective on things.
... and that words like "ecosystem" are being applied should be reason enough to run; it means the bullshit bingo marketing sleaze are taking over.
