Scala has something similar with "placeholder syntax for anonymous functions", where

    _.methodname()

or

    _ + 1

is equivalent to

    x => x.methodname()

or

    x => x + 1

For single placeholders I prefer the look of either the `_` syntax or the alternative some PLs have of `.`.

But otoh, Raku nicely stretches the approach to both zero and multiple placeholders:

* The zero placeholder `.methodname` in Raku is the same as Scala's `_.methodname`

* Any number of placeholders are allowed, so one can write eg `* + *` as an anonymous binary add function.
