#1477: boost::sizer declaration ill-formed
 Reporter: anonymous | Owner: nesotto

Milestone: To Be Determined | Component: range
  Version: Boost 1.34.1 | Severity: Problem
 Keywords: |
 Since the acception of boost::range there exists the file
 (I think it was taken from still older history) which contains two
 overloads of sizer,
 which are written as (I provide only the first overload):

 template< typename T, std::size_t sz >
     sizer( const T BOOST_RANGE_ARRAY_REF()[sz] )[sz];

 This declaration is ill-formed, because it corresponds to a function that
 returns an
 array. The declaration should be fixed to say

 template< typename T, std::size_t sz >
     (& sizer( const T BOOST_RANGE_ARRAY_REF()[sz] ) )[sz];

 (similarily for the other overload). Interestingly, the declaration is
 *not* contained in some detail(s) namespace, but you might consider this
 file to be part of the implementation. In this case another option could
 be to remove this file, although I would regret this choice. Note that
 boost is often quoted in the internet (including this sizer facility!) so
 it seems better to fix the declaration.
