I fail to understand why

convert_to(b, type_tag<A>())

is acceptable and

convert_to<A>(b)

is not in any circumstance.

For what it's worth, I strongly prefer the syntax of the latter -- it works just like the built-in new-style casts and boost::lexical_cast.

Me too. The former is the extended form of the later. They are equivalent. The parameter type_tag<A> is there just to allow ADL. Both forms are allowed by the current implementation in Boost.Conversion. Best, Vicente
