Summary 0001478: [BUG] WeakArray and storeString
Description "Pavel Krivanek" <squeak1@continentalbrno.cz>:
>
>WeakArrays cannot be stored using storeString.
>
>WeakArray new storeString --> '#()'
>
>Pavel

In this case, it should result in something like 'WeakArray new'. Like it
is now, using Object>>readFrom: on the string will result in an Array, instead
of WeakArray.
Steps To Reproduce
Additional Information Tested on 3.8-6665.

Anyway, using storeString with a WeakArray has not much sense:

storeString would not preserve objects identity: code generated would create copies of shared objects when readFrom:

Thus, the resulting WeakArray (if class preserved) would loose all its contents at next garbage collection.

storeString really is a message for simple objects tree. Avoid using on complex object graphs.

See package ProgramRebuilder at VW cincom public store for getting a refactoring idea of storeString.
