questions for docs

[xenoterracide]

is the result of with immutable? and if I call with on the same field a second time will the new value replace the old? how does this work with deeply nested objects/arrays? what if I don't have a no-args constructor?

I think it's worth addressing these in the documentation

[TbotaPhantA]

with mutates any fields and replaces the old value with new one. For example if user name was 'John' and you write .with({ name: 'Jim' }) It will replace the old value with new one.

If you don't have an empty constructor it's not a problem. You create your object however you want and mutate its fields using with method.

I'll put it in documentation later, thanks.
