I\'m reading about extension methods, and monkeying around with them to see how they work, and I tried this:

namespace clunk {
    public static class oog {

    Very clever! A nice attempt, but regrettably we did not implement "extension everything", just extension methods.

    We considered implementing extension properties, extension operators, extension events, extension constructors, extension interfaces, you name it, but most of them were not compelling enough to make it into C# 4 or the upcoming version of C#. We got as far as designing a syntax for the sort of thing you mention. We got rather farther on extension properties; we almost got extension properties into C# 4 but it ended up not working out. The sad story is here.

    So, long story short, no such feature, but we'll consider it for hypothetical future releases of the language.

    You can of course make a "ToBool()" extension method on int if you really do like the retro C convention that non-zero-means-true.
