The scope of Boost.Conversion is not to define specific conversions but
allow to put all the basic type-to-type conversion using a generic
interface. If Boost.Coerce provide an string to type efficient conversion
Boost.Conversion can provide a specialization for string to types conversion
that will delegate to Boost.Coerce. At the end std::string is a type as
others.

Boost.Conversion provides currently and optional (specific file) a
specialization for string-to-type and type-to-string that uses lexical_cast.
It will try to make this specialization available only if the used
expression is valid, but I have no taken the needed time yet.

Best,
Vicente
