[VOTE]About the Union Type for method/constructor declaration

[Daniel Sun]

Hi all,

       I've been thinking about Union Type for method/constructor
declaration. It is similar to multi-catch in try-catch statement, e.g.

class UnionTypeSample {
  public UnionTypeSample(A|B|C p) {
     // do something
  }

  def m(D|E p) {
    // do something
  }
}

      Groovy will translate the above code into the following code, which is
also the same way how multi-catch is handled.

class UnionTypeSample {
  public UnionTypeSample(A p) {
     // do something
  }

  public UnionTypeSample(B p) {
     // do something
  }

  public UnionTypeSample(C p) {
     // do something
  }

  def m(D p) {
    // do something
  }

  def m(E p) {
    // do something
  }
}

     Any thoughts?
----------------------------------
  [+1] I like it
  [  0] Not bad
  [-1] I do not like it

Cheers,
