Manifest code inside a class or definition is processed in lexical
order.
Note also that some programming languages behave similarly to Puppet,
in that their specifications do not require function arguments to be
evaluated in order. C, for example.

This is the usual idiom:
class foo(
$owner,
$user_prefix = '',
$user_etc_dir = ''
) {
$prefix = $user_prefix ? { '' => "/opt/${owner}", default =>
$user_prefix }
$etc_dir = $user_etc_dir ? { '' => "${prefix}/etc", default =>
$user_etc_dir }
...
}
