In simplifying document.open() (see whatwg/html#3946) we would ideally like to have two overloads:
partial interface Document {
[CEReactions] Document open();
WindowProxy open(USVString url, DOMString name, DOMString features);
}
However, according to the overload resolution algorithm, if we did this, calls to document.open("historical", "historical") would throw pretty quickly:
Effective overload set = { open(), open(url, name, features) }
Let maxarg be the length of the longest type list of the entries in S = 3.
Let n be the size of args = 2.
Initialize argcount to be min(maxarg, n) = 2.
Remove from S all entries whose type list is not of length argcount. S = empty set
If S is empty, then throw a TypeError.
Would it be possible to tweak this to allow ignoring extra arguments? That seems more JavaScriptey to me...
Pointers to previous discussions appreciated.
