Nope. It's the _only_ way to define implicit conversions in D. In general, D 
requires explicit conversions in order to avoid all of the problems that 
implicit conversions cause in C++ (e.g. C++ will do up to 3 implicit 
conversions when passing an argument to a function; that gets particularly 
nasty when combined with function overloading; you can quickly have no idea 
what's actually being called without stepping through the code).
