Nope! Static data members have to be defined exactly once in the
whole program. The only exception are constant integral expressions
whose address is never taken: these don't need any definition.
However, addresses are easily taken, e.g. by passing the value to a
function taking an 'int const&' as parameter. The best bet for a
constant integral expression which does not need a separate
definition is using an enum.
