--- Comment #12 from Rajaram Gaunker <zimbabao at gmail.com> ---
@ggaren:
Doing it for document.write because that what is mentioned in spec
https://html.spec.whatwg.org/#dom-document-all
"The user agent must act such that the typeof operator in JavaScript returns the string undefined when applied to the object returned for all."

Are there more such APIs?.

Also at present 
(type=typeof document.all, type === 'function')", "(typeof document.all === 'function') 

return false. Equivalent code pieces giving out different results, which is wrong.

and 

currently typeof document.all returnrs 'undefined'.
