Gepetto is right to flag an error. Puppet does not support parameter
defaults that use the values of other parameters of the same class or
definition. It does not flag a parse error at present, but the results are
undefined. Based on how I think the implementation works, you got lucky on
a 33% chance that your default value would be interpreted as you intended.
There is no guarantee that it will continue to work on a different version
of Puppet or of the Ruby underneath, and it is likely to break if you add,
remove, or rename parameters.
