Subject: WIlderness:: Why do strings when created also seem to create a SHARED

While exploring the ELTS_SHARED flag, I would think the shared object
would only be created
when a string was modified and had more than one reference refering to it.
But it seems that whenever you do this for example
a = "content"
This is created:
OBJ1: basic.flag |= ELTS_SHARED
ptr -> "content"
len -> 7
aux.shared -> OBJ2
OBJ2 ptr -> "content"
len -> 7
aux.capa -> 7
Question: 1) Why do this at the time a string object is created?
2) Do Arrays do the same thing?
3) Other Built-in Types do something similar
(they don't seem to use ELTS_SHARED anyway)
