Maybe we could try the same with D :)

class X {
	void f()
	/+ begin +/
	in {} out {} body {}

	align abstract auto const debug deprecated export extern final package private
protected public scope synchronized struct {
		static union {}
	}

	override invariant {
		asm{}
		try volatile with (typeof(super)) switch(typeid(char) is null) { goto default;
case false: }
		catch { throw new class {}; } finally {}

		delete this;
	}

	unittest {
		for (;;) if (cast(bool)true) {
			do continue;
			while (function(){});
		} else break;

		return assert(delegate void(lazy byte, ref cdouble, inout cfloat, creal,
dchar, double, float, idouble, ifloat, ireal, long, real, ubyte, uint, ulong,
ushort, wchar){});
	}
}
alias int /+ end +/ x;

83 keywords of a possible 98 (unless I missed some). The code compiles with -unittest -debug. There's one warning "switch statement has no default" if compiled with -w, though, so I guess I only get 82 points according to the rules there. :-)

The class is needed only to get the anonymous struct, otherwise it could be all at global scope.

Keywords which can't be used at all:
	cent, ucent, macro

The rest of the keywords need an identifier and thus can't be used without breaking the chain. Feel free to prove me wrong, of course. :-)

I chose to use "alias" at the end there because it happened to be alphabetically
the first. The other options:
	enum, import, interface, foreach, foreach_reverse, mixin, module
	pragma, template, typedef, version, __traits

You could've done 'alias __traits(something...) identifier' instead, for  one extra.

TBH I didn't use __traits because I don't have a 2.0 compiler handy. I didn't know I could do that, cheers. :-)

My mistake; that wouldn't actually increase it, if you're only counting globally reserved keywords.

If you could have an anonymous template, you could do:
mixin (template () { module foo; })!();

Sure it would. "int" can be moved into that delegate and then we'd have __traits in addition to everything I originally used.

Yeah, anonymous templates would chop off a few keywords off the "left-over" list. I'm not sure if putting module in a template like that would work, though, but there are plenty of other options if it doesn't.
