I’m very pleased to announce my first registered Julia package: [RecursiveDicts.jl](https://github.com/mnemnion/RecursiveDicts.jl).

This is a very simple concept (and package): a `RecursiveDict{K,V}` is a `Dict` where the `keytype` is `K` and the `valtype` is `Union{V,RecursiveDict{K,V}}`. This is a useful signature for building tree structures, and operating on them in a type-stable way.

`RecursiveDicts.jl` has no dependencies and should be available from the general registry. I hope you find it useful!
