Hi, Christopher asked me if I would be willing to pursue the submission of this to boost... so I'll give it a shot. Here's what I've managed to do so far: As far as portability is concerned, * Its working and passed basic tests on: - VC6 SP6 - VC7.1 - BCB6 * Compiles ok, but can't be run with: - Como's online compiler (4.33 beta in strict mode) The the runtime tests show significant improvement, as Christopher said, for his original tests, and adding an std::string test shows this version to be roughly twice as fast as boost::any Some thing I would like help on is, is it necessary to ensure alignment for types who's size is <= sizeof(void*) ? The updated version, along with project files for the 3 compilers above mentioned, is available at: http://tinyurl.com/dj5pk or www.geocities.com/pablo_aguilarg/cdiggins_any_update.zip I tried registering at the sandbox, but got an error, I guess I should try later.
