bug#18643: 25.0.50; elisp--expect-function-p

[Leo Liu <sdl.web@gmail.com>]

emacs should only constrain itself to function completion when
absolutely sure.

It is not a big deal if function names creep into variable completion or
vice versa. Often it is handy to complete to an existing symbol and then
edit it into something else. For example, one might need to create a
variable name based on a function name.

There are a few places where I expect to have a completion based on my
past experience but fail now. For example, in (pred ...) pattern of
pcase. Other failures, (let (|)) and (let ((|))) where | is point.

I have experienced annoyances here and there and I think the fundamental
solution is not to second guess but complete liberally as we did before.

HTH,
Leo
