Already several times it was discussed that we might add the `splat` function to Base that would have the following definition:

```julia
splat(f) = x -> f(x...)

```

then we could also consider adding:

```julia
slurp(f) = (x...) -> f(x)

```

(the need for this has not been reported but it is a natural consequence of the first definition)

The question is if such addition to Base could be considered.

`splat` is available nowadays, under the proposed name.

`slurp` is not necessary, instead of `slurp(f)`, just do `f ∘ tuple`.
