There is a gapping hole in the language reference: The

Ok, most of them are the same as in C and C++, but there are
subtle differences (e.g. different precedence) and some are
new (the floating point comparisons have their own chapter and
they are about to beeing deprecated, but what about >>>, ^^,
^^=, =>, ., is, in ?).
And even if they where all the same as in C or C++, not
everybody comes from those languages and D should be
understandable without such kind of background knowledge, I
think.

This describes what operators (tokens) exist and what operands
they can take
(form a grammar point of view), but not what they do. You may say
that's obvious, but I know languages where even "+" doesn't do
what one might expect.

Yes, this goes further into details what operands an operator
take (especially if it is only one or two or more operands), but
not what they do - in this chapter this is especially useless, as
if I overload an operator, it will do whatever I want it to do
even if it is strange as hell. So this is not the right place to
describe the default behaviour of an operator (but ok, It should
refer to that place --- if only there would be one!).
