--- Comment #4 from Travis Leithead [MSFT] <travil@microsoft.com> ---
I think this is a good idea--I was personally always a little turned off by the
throw-on-not-matched behavior of enums (though I understand the rationale for
that).

I'd propose a slight syntax change. Instead of:

enum CanvasContextName {
    "2d", "webgl", default = ""
};

the following seems more appropriate:
enum CanvasContextName {
    "2d", "webgl", "" = default
};

which would allow you to re-use enums for input elements:

enum InputTypeEnum {
    "text" = default,
    "file",
    "submit",
    "range",
    ...[etc.]
};
