-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I am able to modify a const multi_array through a multi_array_ref. For example: const boost::multi_array<int, 2> myarray(boost::extents[2][2]); boost::multi_array_ref<int, 2> myarrayref(myarray); myarrayref[0][1] = 2; IMO, trying to create a multi_array_ref from a const multi_array should fail to compile, only a const_multi_array_ref should work. Also, the reference doesn't include the public inheritance between multi_array, multi_array_ref, and const_multi_array in their class synopses. It is important because it seems to be the only reason you can do conversions from multi_array to multi_array_ref or const_multi_array_ref. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkpDgtMACgkQ5vihyNWuA4VKgACg4+vF6iDMXKgROj6Wl0/sDDWl bZ8AoMDKVcGSY3SWGcRRvaxG6ik8VsPS =A71z -----END PGP SIGNATURE-----
