Block of tasks such a syntax

Hi,
I wonder if following is a valid syntax for creating a block of tasks

`
$ cat playbook-some.yml

Hi,

No.

$ cat playbook-some.yml
---
- hosts: all
  vars_files:
       - ./vars_defaults.yml

  tasks:
    block
    - name: Doing measure A
      import_role:
         name: vendor1.measureA
    - name: Doing measure B
      import_role:
         name: vendor1.measureB
    when: do_measures_a_till_b

Question is about the lack of "- name: some description" line before block.
