Being able to loop/repeat a method|block call in a technique using parameterized local variables would be great.
The loops will be resolved at technique compilation, right before the starting from the leaf element when nested.

The proposed syntax is heavily inspired from the Ansible loops syntax https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html#using-loops.

  - name: "Install a package" 
    method: package_present
    params:
      name: "${plouf.name}" 
      version: "${plouf.version}" 
    foreach:                 # field to force a loop
      - name: "vim" 
        version: "latest" 
      - name: "htop" 
        version: "2.3.4" 
      - name: "${technique_id.extra_package}" 
        version: "latest" 
    foreach_name: "plouf"    # loop iterator name, useful when loops are nested using blocks
