Discussion:
The constructor of reference_wrapper is currently explicit. The primary
motivation behind this is the safety problem with respect to rvalues,
which is addressed by the proposed resolution of the previous issue.
Therefore we should consider relaxing the requirements on the
constructor since requests for the implicit conversion keep resurfacing.
Also please see the thread starting at c++std-lib-17398 for some good discussion on this subject.
Proposed resolution:
Remove the explicit from the constructor of reference_wrapper. If the
proposed resolution of the previous issue is accepted, remove the
explicit from the T&& constructor as well to keep them in sync.
