[range.range] Redundant paragraph about expression variations LWG3915 #4431
Description
Activity
I suppose that the change that clarified the template parameters' cv-qualification for purposes of equality-preservation and requiring additional variations happened concurrently with the change of
std::ranges::range's operand from a forwarding reference to a non-constant lvalue reference.@jwakely , do you feel we can editorially remove p2, or should this get LWG review?
Requested for an issue to be opened.

Expression variations kick in for "an expression that is non-modifying for some constant lvalue operand", but
std::ranges::range's is an non-constant lvalue, so p2 is redundant.
