[boost] Re: lexical_cast with default value

I have earlier suggested that lexical_cast adds locale support so you can 
actually use it to parse something else than unformatted integers but the 
reply quoted the following text from the documentation:

--- Start quote ---

- It is also worth mentioning future non-directions: anything that involves
adding extra arguments for a conversion operation is not being considered. A
custom keyword cast, such as lexical_cast, is intended to look like a
built-in cast operator: built-in cast operators take only a single operand.
Where a higher degree of control is required over conversions, the standard
stringstream offers a more appropriate path. Where non-stream-based
conversions are required, lexical_cast is the wrong tool for the job, and so
it won't be special-cased for such scenarios.
