To be thorough, though, AFAIK "function position" means something 
specific to a Lisp programmer: the first element of a list.

Whereas we also look at whether the whole form is quoted (and if so, 
offer all kinds of symbols as completions anyway), and we can also offer 
function-only completions in a non-function position if the function 
position contains one of the known macros (such as cl-callf or 
declare-function).
