'toString' field removed from cloned object

[assafey]

Cloning an object that includes field 'toString' will have the following affect:
before clone:

[ { a: 'aaa', toString: 'bbb' }, { a: 'ccc', toString: 'ddd' } ]

after clone:

[ { a: 'aaa' }, { a: 'ccc' } ]

'toString' field is removed from cloned object.

Could use hasOwnProperty to tell if a field from Object is being overwritten on the clonee.

@rictic not sure I’m following you. Is it a workaround?

Bump on this, this issue is hanging me up on the development of my programming language.
