Add support for varargs in datatype definitions

[talios]

Would be it possible to add support for varargs:

interface Cases<R> {
  R develop(Job job, Job... dependencies);
  R review(Job job, Job... dependencies);
}

generators constructors like:

public static JobType develop(Job job, Job[] dependencies) {
...

It would be handy if the constructor method matched the vararg definition.

Arrays are painful to work with. I see how varargs can be useful in the constructor signature but I don't think anyone would want to work with them when pattern matching on the datatype. plus that would mean the datatype is mutable...
In your example I think you would be better of using a datatype like NonEmpty<T> that may already provide the varargs constructor.

True - was more just thinking having the consistency would be nice. Maybe a warning emitted if you happen to use varargs?

The code in question I ended up switching for a javaslang HashSet which ended up making the code cleaner in the end as well for other reasons.

I agree that consistency is important, will have a look at it.

I also fixed some non compiling code in generated hashcode/equals/toString in presence of arrays.

Awesome :)
