Bug #19025: inconsistent behavior when using the value of one class parameter
to initialize another

Target version:
Affected Puppet version: 3.0.2

Branch:
The behaviour seen in the test1 and test2 cases below is highly surprising. I
feel that this should either work consistently or the class definition should
fail to compile instead of magically instantiating an undef $y.
$ puppet --version
3.0.2
$ cat test1.pp
class x ($y = 1, $z = $y) {
notify{"y = ${y}": }
notify{"z = ${z}": }
}
include x
$ puppet apply test1.pp
