Emacs should support a c++0x, when it comes to indentation of lamdas and
for_each.

Hi Alan,

This was reported 8 years ago.  Is this wishlist item still relevant,
or has support for this been added since?

Best regards,

I honestly don’t know if this has been resolved. I am fine with this item being closed.

Thanks for reporting back.  I think we should try to get confirmation
that this has indeed been implemented first, so let's hear what Alan
has to say.

In the meantime, it would be helpful if we could have an example of
some code where this indentation applies.  That would help us verify
that it works as expected.  Would you be willing to help provide such
an example?

Best regards,
Stefan Kangas

Nicolai, I'm sorry I missed your bug report originally.  At the time, I
had no idea how to go about implementing (what was to become) C++11.  I
didn't really get started on the job until spring 2012.

Yes, lambda forms and the "colon" form of for:

    for (foo : <collection>) {}

have both been implemented.

There is an extensive regression test suite for CC Mode at
http://cc-mode.sourceforge.net, contained in the CC Mode repository.  It
focuses almost entirely on (static) indentation and fontification.  It
gets updated fairly frequently, as new bugs come to light.

Examples of C++ lambda expression and for statements are in this test
suite.  E.g., forloop-7.cc looks like:

static void DoFoo(const CXXRecordDecl *Class) {
    for (auto *Friend : Class->friends()) {}
}

Thanks; I'm therefore closing this bug report.

Interesting.  I'll try to remember that.
