JavaScript lets you do:

a.map(x => x + 1)

which is pretty nice. And Rust lets you do:

a.map(|x| x + 1)

C++ syntax is just awful, and especially for functional stuff.

Swift closure syntax, at least in <= 2.0, made for awkward API calls, since it wasn’t clear whether inline or after closures were used.

In Ruby,

    a.map(&:succ)

If you have a named function, rust lets you do

    a.map(succ)

as well, since functions can be used where closures can, as long as the types work.

Same in JS
