Two-Level Namespaces

namespaces systems add complexity to the SDK exponentially from their "feature" set.

Personnally, in C, I code my own "name mangling", aka namespace management with the C preprocessor:

#define short_name absolute_path_namespace_name

... code

#undef short_name

The additional work is much less toxic than a full blown namespace system. And I get easy one-compilation-unit code: C applications can grow to extremely large, be fully "componentized" without symbol collision.
