changes I proposed are quite simple requiring little work. As a proof of that I attach lexical_cast.hpp changed to cover what I proposed. I have added classic_lexical_cast which uses std::locale::classic() during the casting. Both version propagate std::locale object to be used. If traditional version is used a NULL pointer is propagated so nothing actually changes and overhead should be marginal. Adding a cat (or other function) which takes arbitrary object should be easy with this code however I have not done it since I don't need it.
What do you think about those changes? Can they be included in Boost 1.40?
At a glance this all seems reasonable and useful, but I am sure everyone is concerned at the risk of causing collateral damage - because lexical_cast is so very, very widely used. Can anyone wanting the new features volunteer to try out your version? I'd like to see some other reports of successful use of this, not necessarily to test the locale features. Would it be wise to do this before unleashing it on trunk to make that it don't cause trouble in the nightly tests? Paul --- Paul A.
