Re: [css-variables] CSSVariablesMap interface doubts

As far as I know, MapClass is not an official attribute right now, but it is 
used to indicate that the class should work in a similar fashion to the Map 
class of ECMAScript 6.

Knowing that, I think the specific case of naming conflicts is therefore the 
one defined in the ECMAScript 6 Map specification.

Subject: [css-variables] CSSVariablesMap interface doubts


I'm implementing the CSSVariablesMap interface in WK. I have a doubt
regarding access to the elements in the map. Previously, if my memory is
not failing me, for a block with a variable declared like

div: {
  var-foo: 10px;

it was specified that one could access it also as a property of the
interface, directly:

Code                      Value"foo")   10px          10px

Is this direct access still allowed as of the latest specifications? I
think it's not entirely clear.

If the answer is yes, what should the behavior be, shall there be any
variable with a name that conflicts with the methods in the interface?

div {
   var-has: 16px;

Code                      Value"has")     ?            ?

Also, and slightly unrelated, in 4.2 there's a text "map tuples" with a
hyperlink that seems to be pointing to the wrong place

Lastly, I seem not to be able to find where MapClass, the extended
attribute used in the interface definition, is defined. Would someone
care to point me out to it?

Thank you,
