I've just tried to use the above test tool, and see the following:
svertka.driver.cpp(127): error in test_svertka: test {result.begin(),
result.end()} == {result2, ...} failed [-431600044 != -78651042]
I think this message misses one thing: the position where mismatch occured. If
svertka.driver.cpp(127): error in test_svertka: test {result.begin(),
result.end()} == {result2, ...} failed [-431600044 != -78651042]
I think this message misses one thing: the position where mismatch
occured. If
differing values are printed, it's natural to print position, too.

While this is certainly quite implementable, I feel a bit uneasy about
hinging variant's exception-safety guarantees on such a small point as
whether 'void' content is allowed. I imagine it would not only make variant
more confusing to use but also may

Please see if you can come up with a simpler non-specific approach
which might break cwpro7. That's what I'd like to have in the
codebase.

But handling at least 2D and 3D C arrays is still acommon requirement.
The problem with 2 or more dimensions is that you

First question: I see that there is a phoenix subdirectory

that pheonix is distributed with boost 1.30.0? or only part of it?

What is this invariant? And why is it that important.

If variant is given types as a MPL-sequence (e.g., variant

can.

Yes, this is the infamous BCC emoticon bug. The parser accepts a number of

I argue that top-level const type arguments are meaningless in the context
of variant. Given the example you provide:
typedef boost::variantint const, std::string const GlobalParameter;
GlobalParameter input_socket(12345);
input_socket = 54321; // no way to prevent this!!
How come!?

visitor( Typelist[MAX_WITCH](storage) );

Your pseudo-code is misleading. There is no MAX_WHICH available to the
preprocessor when MPL-sequences are given because there is no theoretical
upper limit on the size of a
