Options, unlike arbitrary variables, come with a type declaration.  Some
options come with setting mechanisms, again unlike arbitrary variables.
No dramatisation here.  Just a statement of facts.

Sure, setq, as you say, works, but neither does it check that the values
assigned to an option belong to the declared types, nor does it respect
the setting mechanisms of options.  I would prefer to heed these
features when I assign values to options, so I have been asking about
alternatives to setq like customize-set-variable.

I asked explicitly in my first message about a "recommended way of
setting an option using Emacs Lisp directly".  I don't remember saying
that I want to set options or variables interactively.

Cheers,
