I feel that C++ messed up namespace design because:

Namespaces are not as powerful as they could have been, but being able to add
symbols to an external scope (like classes) is very useful if done right (e.g.
cross-cutting enhancements, adding members to external classes like
"saveyourself", "printyourself").
It's seriously wrong to allow such. It makes a larger code base nearly
impossible to reliably reason about, leading one to rely on conventions like
"don't add stuff to namespaces".
D has closed scopes, and members can be "added" to external classes just fine,
using CTFE.
