Yes, I noticed that, and I thought that this is not a problem, because
BOOST_STATIC_CONSTANT should be used to define only "true" compile-time
constants, the ones that are intended to be used in integral constant
expressions, and why one would write a runtime check when a compile-time one
is available anyway? :). But probably where are cases when people do want to
do that (numeric_limits<> users?), so I am inclined to think that the
proposed resolution of the issue is an unfortunate one. In particular, text
at the beginning seems to be much more reasonable:

In particular, if an integral/enum const static data member is initialized
within the class, and its address is never taken, we agreed that no
namespace-scope definition was required.

Are there any ways to re-open the issue?
