How!? Please Explain. You need to demonstrate evidence instead
of appeal to emotional fallacy by resorting to "feels".

The DIP increases consistency recalling that rvalues are
accepted:
- for the implicit 'this' parameter in methods
- in foreach loop variables declared as ref
No more special rules: rvalues are implicitly promoted to
lvalues where needed.
That's correct, but 'this' is already a special guest in C++
style PL, with its own special rules. The support for ref
variable in foreach loop.... can be removed (yup!), or made
stricter.. no more inconsistency.
The feeling probably comes from the
inevitable realization that the community is pluralistic and
Dlang acquired a lot of features that go towards someone else's
vision for a good PL. Some want a relaxed stance towards
breaking change, some want C++ or ObjC compatibility, some
want to know what assembly a piece of code compiles to or have
soft realtime constraints that don't work with a system
language's mark&sweep GC. Is D2 messier than D1? Sure it is,
and it caters to more use cases, too. As soon as you
substantiate what exact feature is adding to the horrible
mess, someone (often a group) will jump to defend it, because
they have a good use case or two.
Yep, and I'm conscious to be often a pessimistic, lurking guy
here in the forum... :-/
It is kind of ironic that in order to do better than C++ you
have to support most of what modern C++ compilers offer and end
up having tons of unrelated features that make the language
just as bloated as C++ after a decade of community feedback.
It is a system PL. I think it needs to be this way and is a
lot cleaner with basic data types and more expressive still,
lacking a lot of C++'s legacy.
There's a tension between Walter effort in turning D as a
suitable language for memory correctness, and a good candidate
for writing 'bug free rock solid software fast' and the
continuous addition of features like this.
Joke aside, I'm still on Jonathan side on this.
Finally, sorry to use often the term 'feeling', and sorry for not
being constructive: but really is a 'feeling'... I don't pretend
to be right. So no problems in just ignoring that
:-P
Cheers,
Paolo
