Hi,

I find that I can't write

static_assert(N > 0);

in Visual Studio 2010. This seems to be consistent with the current C++
0X draft: the error message is required:

static_assert(N > 0, "N must be a positive number.");

However, I would like it convenient if static_assert without a message
worked as STATIC_ASSERT below:

#define STATIC_ASSERT(x) static_assert((x), #x)

STATIC_ASSERT(N > 0);

This is because many of the tests are simple and self-explanatory, and
stringizing the condition is a reasonable default error message in these
cases.

What do you think?

I think that this is a very reasonable default. Boost also uses it,
if possible:

#define BOOST_STATIC_ASSERT( B ) static_assert(B, #B)
