I wanted a no*-op script the other day:

  script:
    - true  # oh no*

No* pun intended.

*Pun also intended.

(To the uninitiated: YAML automatically casts the bare string “true” into a boolean for you. Fairly reasonable. But it does the same with “yes” and, per the parent comment, “no” too. This is problematic if you have a list of ISO language codes including Norwegian.)
