* `try_lexical_cast` must be added or not? And if yes, what signature is
preffered:
bool try_lexical_cast(Out&, const In&)
bool try_lexical_cast(const In&, Out&)
boost::optional<Out> try_lexical_cast(const In&)
How about:
boost::optional<Out> lexical_cast(const In&, std::nothrow_t)
This will break one of the use cases. For example there'll be an ambiguity
beacause of function overloads.:

std::transform(
  values.begin(), values.end(),
  ret.begin(),
  &boost::lexical_cast
);
