The problem with these declarative methods is always leaving the object in a incomplete state. I prefer factory methods with private constructor myself. Hide the instance, so that immutable object tricks can be used, but still use descritive function names. Plus if you're using generics you can use the limited type inference that java has. Do you prefer new Tuple<Int,Int>(a,b); or Tuples.pair(a,b) ?

Cf. Item 2 in Effective Java 2nd edition (also you can see it here - http://rwhansen.blogspot.com/2007/07/theres-builder-pattern-that-joshua.html). The idea is the same but moving this into Builder seems like nicer solution.
