# All checkers turned on, minus:
#  * Proper header guards used (the check is very brittle and incorrectly assesses my guards)
#  * Use of "using namespace" (the check fires even on non-global using namespace, which is daft)
#  * Copy and paste detection (the check fires on unit test code which is by its nature very copy and paste)
#  * Use of traditional integral types
#  * Array to pointer decay (the check fires on static constexpr string arrays, daft)
#  * Unreachable code (the check is too naive and misses CRTP injected code)
#  * Use after move (my unit tests test semantics when you do this, most shouldn't need to disable this)
#  * Use of printf
#  * Use of push_back instead of emplace (unhelpful check, emplace isn't exception safe like push_back)
#  * Throwing exception objects which aren't nothrow copy constructible (Dinkumware STL does this, not my fault)
#  * modernize function style to C++11 trailing return type
#  * disallow usage of implicit optional arguments in calls
#  * remove "method must resolve to a function within the __llvm_libc namespace" warnings

# Like in https://github.com/Kitware/CMake/blob/master/.clang-tidy
#   pattern should be filtered as `find | grep -E PATTERN` do
# Unfortunately, I did'nt succeed to enable it and filter out armadillo headers
