@Krux02 I disagree with your assessment. It is true that both representation types (tuple and arithmetic) are valid. However one of them is much more used both in real life (i.e. people doing arithmetic on paper) and in those programming languages that have made good math support one of their key objectives.
I think the "echo" advantage is quite minor, and is much less important that simply being able to view complex number using their usual "paper" representation. This is even more important now that there are projects to create a Jupyter nim kernel, for example.
