Description Erik Arvidsson 2013-04-11 22:16:12 UTC 
Interface objects are Functions with a [[Call]] behavior that throws by default.

http://dev.w3.org/2006/webapi/WebIDL/#es-interface-call

Therefore typeof HTMLElement === "function".
Comment 1 Cameron McCormack 2013-04-11 22:38:06 UTC 
That should already be required, since http://dev.w3.org/2006/webapi/WebIDL/#interface-object says that the interface object is a function object, and http://dev.w3.org/2006/webapi/WebIDL/#dfn-function-object describes those.  (It has some out of date ES6 terminology that needs updating, but hopefully it is still clear.)
Comment 2 Cameron McCormack 2013-04-11 22:39:32 UTC 
Do you just want a clarifying note pointing out that "typeof <interfaceobject>" will be function?  I can add that, though I think it would be better place in the preceding section http://dev.w3.org/2006/webapi/WebIDL/#interface-object.
Comment 3 Erik Arvidsson 2013-04-12 17:10:04 UTC 
I just thought a note would be useful since more than one smart person failed to come to this conclusion after reading the spec.
