(function(){"use strict";}).hasOwnProperty('caller')
TypeError: Cannot access caller property of a strict mode function

The problem also occurs for other operations besides 'in'. Again, as with 'in', the poisoning of 'caller' should not prevent hasOwnProperty from working as specified. hasOwnProperty must not attempt to access the property's value.
