Sorting of equal quality about negotiator HOT 4 CLOSED

I couldn't find anything in the specs saying that the languages that appear first in the Accept-Language header should have higher priority than the rest.

I would consider making this change if there was any indication that this is expected in practice but I haven't found anything so far.

To help decide, from RFC 7231 5.3.5:

Note that some recipients treat the order in which language tags are listed as an indication of descending priority, particularly for tags that are assigned equal quality values (no value is the same as q=1). However, this behavior cannot be relied upon. For consistency and to maximize interoperability, many user agents assign each language tag a unique quality value while also listing them in order of decreasing quality. Additional discussion of language priority lists can be found in Section 2.3 of RFC4647.

i'd prefer not to make this change and return types as i, the developer, supplies them to negotiator

That would be nice, but this is exactly not what V8 does. Array#sort changes the original order. Which means you can not assume.
