[expr.prim.id] Fix immediate function id-expression requirement #3244
Conversation
|
Without expressing any opinion re whether we want some such rewording, the proposed placement of "only" is suboptimal. To say that something "shall only appear ..." implies, for example, that it mustn't cook, clean, play, tap-dance, or snore -- the only thing it can do is appear. If we decide that we do want a wording adjustment hereabouts, please consider injecting "only" in two places within this sentence: "... shall appear only as a subexpression of an immediate invocation or only in an immediate function context\iref{expr.const}." I'm less unhappy with that, but the sentence is too long, with too many qualifying phrases, to move "only" to the sentence end as I'd truly prefer. It would be easiest if we had a short bullet list here: "... shall appear only: (bullet a) as a subexpression of an immediate invocation, or (bullet b) in an immediate function context\iref{expr.const}." |

There was a problem hiding this comment.
I like Walter's suggestion of adding bullets and moving the only a little farther towards the end.

Move possibilities into a list, and add "only" after "appear". Reason for being editorial: not intent to require all programs to use an "id-expression that denotes an immediate function", and moving the possiblities into a list does not change the meaning.

Reason for being editorial: It is probably not the committee's intent to require all programs to use "an id-expression that denotes an immediate function".
