I don't. I write C++ code for my day job, and I'd have to say that
these revisions make C++ better than ever to write. It's cleaner,
simpler, and more maintainable. Just last week I wrote some prototype
code in C++11, and later had to change it to use C++98 features to
comply with the project's requirements. It doubled the line count and
made it vastly less readable, and this was using only two features: auto
types and range-base for loops. The benefits it provides are not
insignificant.

When you say they are "nuts", are there any changes in C++14 or C++17
which you have found to be ill-considered? While no standard is ever
"perfect", I have no complaints about C++11 or C++14. Since these are
ISO standards, the realities of the process means there's little scope
for pushing in lots of poorly thought out changes at the last
minute--most of the changes have been planned and implemented for many
years. There's only one feature I can think of which was bad--template
export--and this was in C++98; and I think they learned their lesson
from that one--never put in a standard a features which hasn't been
implemented and tested in the real world.
