(This part of the discussion on zsh-workers.)

If it seems worth doing, expanding doshfunc so the last argument is a
set of bit flags and adding an argument to runshfunc to indicate a
context that would show up in the appropriate place in $zsh_eval_context
(potentially useful for modules to make functions called in a particular
way easy to detect) isn't hard. But if it's more churn that people won't
actually use much it's probably not worth doing.
