Hi,
during the Boost.Convert after review discussion there were some proposals to use Boost.Phoenix to build the functors.
My question is what should be the name of the function that builds the functor. Some possibilities:
short s=1; long l=3; using boost::phoenix::placeholders::_1;
A- Use a different name: make_converter_to?
s=boost::make_converter_to(*short*)(_1)(l) ;
B- Use the same name in a different namespace. What about using "fp" as namespace (functional programming).
s=boost::conversion::fp::convert_to(*short*)(_1)(l) ;
Proto uses a separate namespace boost::proto::functional for such, so I think it's OK for Convert as well, while 'sp' is being too succinct, I think it'd be better to leave such tiny naming for the users themselves. If 'functional' is too long, maybe 'lazy' is a good choice...If this is your decision.
C- Use the same name in the same namespace and use SFINAE/enable_if to select the correct implementation depending on the parameter.
Maybe it's just a simple overloading without SFINAE. But this may imply that it's tied to Phoenix actor...
