// Blanket implementation for all Sized TypeInfo types to convert to a &(dyn Any + Sync). This 
// leaves the possibility of other implementations for other types T: TypeInfo + ?Sized, but as the
// Registry trait requires Self::TypeInfo: TypeInfo + Sized, these other implementations cannot
// be used with this crate. The notable exception being dyn TypeInfo, but its implementation is
// deferring to this one as required.
