So what else can be a key in Python dictionaries exactly? The documentation mentions a tuple of immutable objects, which I guess can have its uses, but saying that javascript does not have dictionaries (or only "dictionary-like" objects) because of this seems a bit over the top to be honest. > > I'm sure there are implementations of sets around for JavaScript.

If you feel this is important you can always open a bug and suggest an implementation to the Seed guys.

In any case, as before, the only way to improve things is to contribute. Basically I'd say that all our problems at the moment come from the fact that Seed is still a pretty new project in need of a lot of work to mature, and that JavaScript is a perfectly adequate language to write extensions or even large parts of the core of a browser (like Firefox). > > /M > > -- > Magnus Therning (OpenPGP: 0xAB4DFBA4) > magnus＠therning．org Jabber: magnus＠therning．org > http://therning.org/magnus identi.ca|twitter: magthe > _______________________________________________ epiphany-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/epiphany-list
