Javascript: first release was 1995, making it 25 years old. It's older
than most Javascript programmers.
Kotlin is only 9 years old. But Scala is 17 years old.
(By the way, Julia calls the -> arrow "the stab operator". I think
that's amusing.)
Python has a long history of taking inspiration from other languages,
but we've had anonymous functions for longer than Javascript has
existed. This proposed arrow function would just be an alternative
spelling for the same thing. It adds no more power, and no more
expressiveness to the language.
It would be just one more thing to learn, one more decision to make
("lambda or arrow?"), one more question to be asked a thousand times
("what's the difference between lambda and arrow?").
