I also think this, or something like this, should be the way to go.
For me this could become the final lua solution. Somehow similar
proposal was in http://lua-users.org/lists/lua-l/2018-03/msg00395.html
.
Glad someone else has had the same notion!
I don't care for this
#tab = nil
Resetting # to the default behavior. That should actually set the return value to nil.
It's already a little odd[*] having something be an assignment on the left side and
effectively a function call on the right. Having the implementation silently change the
assignment to something else would be surprising.
[*] Not so odd in Lua, where we can use __newindex to do this as well.
I really would like to hear by the lua team why this kind of solution
was discarded (I am quite sure they already examined it).
