Block 1:
class infra::agent_dir_structure (
    $agent_dir_structure_list = $infra::params::agent_dir_structure_list,
) inherits infra::params {
    $agent_dir_structure_list.each |$dir| {
        file { $dir:
            ensure => directory,
        }
    }
}

Block 2:
class infra::agent_dir_structure () inherits infra::params {
    $agent_dir_structure_list.each |$dir| {
        file { $dir:
            ensure => directory,
        }
    }
