>Go [...] there was not much I saw the language could teach me
Interesting that you mention this; one of the reasons I really enjoy Rust is because of how it forces me to think through things more clearly, and how a number of the higher-quality crates teach more advanced approaches in a straightforward way.
I am a Python programmer first and foremost (data science-y stuff), but lately I've started reading the Rust documentation. First and foremost its really an enjoyable read. I also learn alot from it, and become a better programmer in general. I will try to write a library that I will use for my PhD, in Rust. I think it will teach me a lot about programming, be enjoyable and also give me a great library for string parsing and decryption.
