description: >
If the left-hand side is not a lexical binding and the assignment produces
an error, the iterator should be closed and the error forwarded to the
runtime.
info: |
...
If destructuring is false, then
If lhsRef is an abrupt completion, then
Let status be lhsRef.
Else if lhsKind is lexicalBinding, then
Let status be InitializeReferencedBinding(lhsRef, nextValue).
Else,
Let status be PutValue(lhsRef, nextValue).
