Someone was asking me today about the inefficiency of lexical_cast for its common itoa/atoi-like usage, and it occurred to me that it could *easily* be optimized to handle the common cases by dispatching to itoa/atoi ftoa/atof where available, and even sprintf. Seems like a great idea to me.

I'd quite like to know if Johan got these changes into the library. Any news on this?
Please do not proceed at the expense of error handling. I believe using itoa and ftoa is fine, but using atoi and atof is definitely not: cout << atoi("123X") prints 123 cout << atoi("X") prints 0 lexical_cast<int> throws in both cases, which I think is 100% the correct behaviour. --> Mika Heiskanen
