-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 multi_array and friends should provide the number of dimensions as a static member constant, so it is available at compile time and can be used in generic programming. I assume the num_dimensions() non-static member function was put in the design with the idea that the number of dimensions of a multi_array object might be dynamically changed. But since the multi array concept and classes doen't support changing the number of dimensions, it doesn't provide anything useful over a static constant. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEARECAAYFAkpE4poACgkQ5vihyNWuA4VzQgCfcbKVf2y10seFT7M+fAEkAHr9 KkAAniIZCuLumjb2VcVJgDF6BZMtalfb =wyei -----END PGP SIGNATURE-----
