Well, but that is useful feature and this is one of things I like with C++ - the "default" mode is "safe", but you can always do dirty things when you need them.

no, here I don't agree.... such things make virtually impossible write 'safe' libraries. A 'const' should be a 'const', not a 'maybe const'.... as 'private' should be so, not a maybe one.
I've seen constructs like that :

#define private public
#include "alib.h"

just to overcome a private class declaration and access the low-level stuffs inside it.... Then, when library changes, people (maybe also people that hasn't nothing to do with such a hack) starts wondering why his program that up to the day before worked like a charm just crash. IMHO that has nothing to do with commercial-grade applications.

Sure, this is awful, but very often, the alternative is that it is not possible to finish your job.

Note that all these "high-level" language, whose propagators despise C/C++, have interfaces for these languages so that the dirty stuff can be done.

well, a well written lib should do what the coder will, *not* what the user is missing. Before using C++ hacks to overcome libs limitations, you have 3 solutions :
1) Patch the sources, if you have them
2) Ask the original programmer to enhance the lib
3) Just find another lib that suit your needs

And if neither is possible? You quit the job?
