There's nothing wrong with it at all.
But often, questions arise from some other circumstances and this one is
of such a flavour that if you wanted this code in a real application it
would _often_ be the wrong solution to seek, because normally you know
how to call something - it is not normally useful to introspect it to
decide what to do.
So I was wondering what the outer context might be, because there may
