If there is a consensus that arrows are better enough that lambdas, and
arrows happen, lambdas will be considered 'old' and automated converters
such as pyupgrade will be quick to replace lambdas (and people publishing
libraries will have to wait until the EOL of the older versions of Python
before being able to run it).
And if, otherwise, there is no such consensus, the change will never happen.
Same as u"xxx" versus Unicode("xxx"), x**y vs pow(x, y), x @ y
vs. matmul(x, y), etc.
