One could consider it a bug that object.size(cx) is indeed
inspecting every string, i.e., accessing cx[i] for all i.
Note that it is *not* deALTREPing cx itself :

Objectsize function visiting every element for alt-rep strings
I have a toy alt-rep string package that generates randomly seeded strings.
example:
library(altstringisode)
x <- altrandomStrings(1e8)
head(x)
[1] "2PN0bdwPY7CA8M06zVKEkhHgZVgtV1" "5PN2qmWqBlQ9wQj99nsQzldVI5ZuGX" ... etc
object.size(1e8)
Object.size will call the set_altstring_Elt_method for every single
element, materializing (slowly) every element of the vector. This
