Re: ref to read-only alias ... why?by LanX (Bishop)

It appears like read-only values are not modified when aliased.
Seems to me like "aliasing" read-only values is falling back to "copying".
Or in other words: Only lvalues can be "really" aliased.
Which makes sense in a way, because the original value can't be changed anyway.
