Hi @GrayJack , Can I work on this?

[GrayJack]

Yes, of course 😄

Hi, sorry for the inactivity on this issue. I haven't had the time to work on it yet. Also, I've seen that unexpand has already been implemented. So, if @bojan88 (whom I know from another project) wouldn't mind, he can implement this one as well :) .

Please, feel free to implement it. Of course I don't mind.
I might join for code reviews

It's best that you do expand as it'll be very similar to unexpand and you already own the code for that. I won't like to have my name on it, if I just mostly copied your code. I'll find some other issue to work on some other time 😉.

[GrayJack]

In that case, if most of the code is copied, is just a matter to put his name (with yours too) on the crate and author text 😄

As long there is a proper attribution, I really don't care who made the PR

[bojan88]

I also don't mind if you copy most of my code.

[muskuloes]

Alright guys. I'll do it in the week. @bojan88, I'll add your name as author and will appreciate you reviewing the PR 😅.
