Does this function exist already somewhere?

```julia
mapsplat(f, xs...) = map(Base.splat(f), xs...)

```

Pretty sure this doesn’t exist in baseline Julia. But you can certainly define it for yourself.

For something this easy to assemble, it seems unlikely it would be added unless there was a notable performance benefit or some other compelling reason.
