The only exceptions are: - The purpose of the header is to drag in the used symbol, e.g. unique_ptr.h - The used symbol is inside a class or a namespace other than lyx The reason for this is that global 'using' statements effectively forbid to use the used symbols in any other namespace in the whole program, since simply adding or removing an #include of the corresponding header subtly changes the name lookup. The namespace lyx is sort of global, so it should not have these statements either.
