I learned Rust before learning C properly.

Oh boy. I see bugs everywhere in C and why the borrow checker exists. It really forces you to understand what happens under the hood.

The most issues in Rust are indeed related the expressions - you don't know how to describe some scenario for compiler well-enough, in order to prove that this is actually possible - and then your program won't compile.

In C, you talk more to the computer with the language syntax, whereas in Rust you talk to the compiler.
