As to the error handling - I haven't personally given it much thought - but I'm not sure that can be easily parameterised without disturbing the interface.
Another nice feature would be to check if the output was actually generated from the complete input. Imagine the following scenario: You have lexical_cast<double>("1,2") and as it happens, it returns 1 but happily. This is why I used strtod directly in an application of mine. You could add parameters with Boost.Parameters, by the way. So I would call: lexical_cast<double>("1,2", ignore_tail = false) and get a exception. I will probably have to wait for Boost 1.36 though :D.
The LWG is also moving forward with a separate set of conversion functions that are lower level, consume the input string (if any), and in general are to be used where lexical_cast is not the right tool. There will be a paper from Pete Becker available in two or three weeks. --Beman
