description: >
Abrupt completion when Symbol.toPrimitive returns an object
info: |
Runtime Semantics: TrimString ( string, where )
1. Let str be ? RequireObjectCoercible(string).
2. Let S be ? ToString(str).
...
ToString ( argument )
If arguement is Object:
1. Let primValue be ? ToPrimitive(argument, hint String).
...
ToPrimitive ( input [, PreferredType ])
...
d. Let exoticToPrim be ? GetMethod(input, @@toPrimitive).
e. If exoticToPrim is not undefined, then
i. Let result be ? Call(exoticToPrim, input, « hint »).
ii. If Type(result) is not Object, return result.
iii. Throw a TypeError exception.
