I have a proposal for new syntax in ES inspired by the placeholder syntax
in Scala Functions
<http://docs.scala-lang.org/overviews/quasiquotes/expression-details.html#function>
.
Essentially, the idea would be to allow anonymous arguments. The most
simple example would be a function which takes one argument (as far as the
programmer is concerned):
[1, 2, 3].map(@ + 1)
This would be the same thing as:
[1, 2, 3].map(n => n + 1)
Just like in Scala, an anonymous function is created. This concept can be
further extended in ES:
[1, 2, 3].reduce(@0 + @1, 0)
Which would be the same thing as:
[1, 2, 3].reduce((sum, n) => sum + n, 0)
Thoughts?
