‘Helper’ functions in C++

Overhead is not an issue, namespaces have some advantages though

• You can reopen a namespace in another header, grouping things more logically while
  keeping compile dependencies low

• You can use namespace aliasing to your advantage
  (debug/release, platform specific helpers, ….)

  e.g. I’ve done stuff like

  namespace LittleEndianHelper {
     void Function();
  }
  namespace BigEndianHelper {
     void Function();
  }
  
  #if powerpc
     namespace Helper = BigEndianHelper;
  #elif intel
     namespace Helper = LittleEndianHelper;
  #endif
