[gmx-developers] C++11 in master

[Roland Schulz]

Hi,

what is the policy for C++11 features in master? Is it OK as long as it
available in our actively supported compilers, and is a feature which is
not complicated and makes the code easier (simple C++ idea)?

Specific I'm asking about:
- auto (type interference for initialization, simplifies code especially
with iterators)
- std::array (fixed size array. Not the overhead of vector but the safety)
- std::tuple
- cstdint/cinttypes (mentioned at open question at
http://www.gromacs.org/index.php?title=Developer_Zone/Programming_Guide/Allowed_C%2B%2B_Features
)

These are supported by GCC (>=4.4), Intel and MSVC. Also all but auto are
in tr1 and thus also available in boost in case a compiler would not
support it.
