As a programmer I think it's notable that when I learned Rust I wanted to rewrite stuff in Rust.
I rewrote 'leakdice' as part of learning Rust, so arguably that doesn't count (though I had never rewritten a program to learn a previous language), and 'misfortunate' wouldn't make sense in unsafe languages so that doesn't count either, but I then also immediately began rewriting 4store in Rust.
I had never been compelled to rewrite stuff in other languages I learned. I am a compulsive programmer, so I did write stuff in languages I learned, (the other day I re-discovered, via an enquiry to a very old email address, that I used to know Scheme, as evidenced by the fact I wrote some Scheme that they were asking about from last century) but I didn't rewrite anything until I learned Rust.
C. Go. Python. Java. PHP. Bash. Perl. C#. Early C++. I'm sure there are many more. But always new things, either because the language afforded something I hadn't considered before or more often I wanted something and I chose a languages I knew would be able to achieve it. That's why I wrote some PHP less than a year ago, I'm not proud of that, but PHP got the job done so that's what I did. I can report that modern PHP is merely a bad idea, like Javascript, which I probably forgot to list above.
Anyway with Rust I not only wanted to write new low-level code in Rust, I looked again at C programs I use and thought, "I should rewrite that in Rust". It felt like a good idea, and I expect to follow through on it at least somewhat, let's see how long 4store takes.
