--- Comment #5 from C. Scott Ananian <canan...@wikimedia.org> ---
The standard thunk is something like:
function Map() { this.store = Object.create(null); }
Map.prototype.get = function( k ) { return this.store['$'+k]; }
Map.prototype.set = function( k, v ) { this.store['$'+k] = v; }
...but we should be a little careful not to go overboard here. In many cases
we know that '__proto__' cannot be a possible key. In other case we are doing
queries only (for example, to determine whether a tag name is a member of a
specific set), and Object.create(null).__proto__===null, so that's perfectly
safe as well.
So, sure we should use safer maps where needed, but it probably doesn't have to
be a hugely-invasive patch set.
