I don't do C++, but Garrett the uClibc++ maintainer used to be at the desk 
next to mine.  He would find this statment hilarious.

Among other things, any _sane_ C++ ABI will deal with nested classes and 
namespaces by listing the innermost one first, so that when you have:

parent1.parent2.parent3.child.member
parent1.parent2.parent3.child.walrus
parent1.parent2.parent3.child.thingy

You don't strcmp your way through 80 bytes of guaranteed-to-be-identical data 
every time you want to do linking or RTTI or anything that needs to find a 
symbol.  This is just one random example of how the people who were doing 
this weren't THINKING.

I'll stop now.
