Oneway builder

[michaldo]

The benefit of builders is readability, but there is a risk of missing parameter. Constructor is less readable, but compiler ensures all parameters are present.

Did you consider oneway builder?

Example:
public record NameAndAge(String name, int age){}

Oneway builder is something like

interface NameAndAgeBuilder {
  AgeBuilder name(String name);
}
interface AgeBuilder {
  NameAndAge age(int age);
}

usage:
NameAndAge foo123 = NameAndAgeBuilder.builder().name("foo").age(123);

Oneway builder has both: readability and completeness. Completeness, because to get NameAndAge you must follow path name(...).age(...) and there is no other path to create NameAndAge object.

That would be a lot of extra classes to make work. I think it's out of the scope of this project.
