Describe the solution you'd like
I'd like to be able to change the street names, and/or add streets.

Set lazy value which is different when call set and call sample
New operation would determines value when call sample

As is

// given
ArbitraryBuilder<String> variable = fixture.giveMeBuilder(String.class);
ArbitraryBuilder<String> builder = fixture.giveMeBuilder(String.class)
    .set(variable.sample());
variable.set("test");

// when
String actual = builder.sample();
