I think the question was how you can access a field in an object through a variable holding the name of the field.
Unfortunately (at least in this case, most often it is very fortunate) Nim is a statically typed compiled language, so the names of fields aren't really accessible at runtime. You could of course achieve similar things through meta-programming, but before reaching into that I think it's wise to look at what you're actually trying to achieve. What is the problem you're trying to solve by doing this? There might be a way to do what you want in a way that's more suitable.
