I am wondering if I can write a script that both adds and precompiles a set of packages. Alas

```julia
s= "CSV"
Pkg.add(s)
using s

```

does not work, because s is considered a name. is there a callable string method to the `using` command?

```julia
packages = ["CSV", "JSON"]
Pkg.add(packages)
Pkg.API.precompile()

```

The `API` should not be necessary but it is right now because of a forgotten import.

Is this forgotten import being fixed in 1.0.1? It doesn’t bother me to do it via `Pkg.API` but I want to know when I should clean up the code. Thanks
