yes, avoiding runtime costs is the real problem.

docstrings are mostly oneliners (at least in elisp)

Other applications are methodbrowsers/tabexpansions showing additional infos.

Or tooltips in IDEs when hovering the mouse over a method call.

PODs are not DRY, the subname must be repeated, docstrings are automatically at the right place.
