When I do want to define my own custom getter, how might I tell the
language that my new method is a custom getter and not just a method with
no arguments and one return value? I think if Go were to have properties,
they would have to be explicitly marked as a property in some way to avoid
this.
For what it's worth, I'm personally mixed on properties. They do provide a
nice syntax for accessing information from an object but they can sometimes
make it harder to see what's going on in a program. When I read code in
languages with properties, it can be hard for me to know which expressions
result in some external code being run and which ones don't.
