True, but TBH that is IMHO the least important aspect of the proposal.
I'm much less bothered by repeating a name than by having to use a
member function when what I really want is read-only access to a member
variable. The latter affects *my users*. The former only affects me.
Combine that with other features of my (counter)proposal:
- Does not need new keywords.
- Does not add an ambiguity issue for derived classesÂ¹.
- Looks similar to, or can be implemented using, a feature that has
already been proposed and is more widely useful.
