Discussion – references to additional in depth rationale and/or examples placed outside the principle lists of regulations
Old behaviors die tough, so this rule is tough to use constantly, In particular as there are plenty of instances wherever = is harmless.
Talking of lambdas, what would weigh in on the choice involving lambdas and (nearby?) lessons in algorithm calls together with other callback situations?
It’s fantastic to return a smart pointer, but compared with with Uncooked tips the return type can not be covariant (by way of example, D::clone can’t return a unique_ptr.

Think about putting each definition within an implementation resource file in an unnamed namespace Until which is defining an “exterior/exported” entity.
Flag declaration of a C array inside a perform or course that also declares an STL container (to avoid extreme noisy warnings on legacy non-STL code). To repair: At the least change the C array into a std::array.
Instruction reordering (static and dynamic) can make it tough for us to think effectively at this level (particularly if you employ pop over to this site comfortable memory designs).
that make using one of the most mistake-vulnerable features of C++ redundant, to ensure that they can be my latest blog post banned (in our set of policies).
What appears to be to your human similar to a variable without having a name is to your compiler a statement consisting of A brief that promptly goes away from scope.
Const member features should be thread Secure … aka, but I don’t genuinely alter the variable, just assign it a price the first time it’s called … argh
