Thanks Jose for your answer.
The note from the doc is quite vague in my opinion. I would understand that
class c1 {
class { 'c2' : }
require "c3"
}
effectively mixes the two behaviors, but
class { 'c1' : }
class c1 {
require "c2"
}
should not be a case of mixed behavior. The following is equally incorrect
then?
class { 'c1' : }
class c1 {
anchor { 'c1::begin' } ->
class { 'c2' : }
}
class c2 {
require "c3"
}
What if I have 2 classes coming from 2 modules, one that needs parameters,
the other that don't but uses a require:
class moduleA( $param1 ) {
}
class moduleB {
require "someOtherClass"
}
class myClass {
class { 'moduleA': param1 => 'stuff' }
# oops... mixing the two behaviors...
class { 'moduleB' : }
# should be
# require 'moduleB'
# but that would mix the two behaviors as well...
}
