I would prefer the default includes exactly the expressions/syntax that C++ provides by default, which may mean writing some inline here though I'm perplexed that we need to do something different to clang compiling c++. I'd have to look up which operators are magic and which are in the header.

At least some reluctance is that we don't have a gpu <new>, so this will be whatever host libstdc++/libc++ is in use, and I'd like to avoid including gpu-unaware code on the gpu wherever possible.
