I’m very pleased to announce the **[RandomExtensions.jl](https://github.com/rfourquet/RandomExtensions.jl)** package: this started out as a PR against the `Random` module before the 1.0 release of Julia, which was wisely not merged.  
But after a couple more iterations on the design, it now feels ready for public consumption. My hope is that user feed-back will allow eventually to incorporate back some functionalities into `Random`, in some form or another.

Essentially, it allows to create new “scalars”, like pairs or tuples, via a `make` function:

```julia
julia> rand(make(Tuple, 1:9, UInt8, String))
(2, 0xf4, "0CLgPODQ")

```

and extends the rand API to allow creating other containers than arrays:

```julia
julia> rand(make(Pair, 1:9, UInt8), Dict, 3)
Dict{Int64,UInt8} with 3 entries:
  9 => 0xc4
  3 => 0x92
  5 => 0x11

```

This is of course easily extensible for user-defined types. See the README for more examples. Bug reports and contributions (code or ideas) are very welcome!
