Hi ruks, If you are going to rely on explicit template instantiation, you have to be meticulous about instantiating all the templates that are referenced. And you have to have a deep knowledge about the template mechanism (which* is a an obtuse, convoluted, and confusing code generation language built into C++ -- but x1000 better than the C preprocessor). Otherwise, in my opinion, it is best to rely on implicit template instantiation and vague linkage instead. I am not a C++ template guru. I know enough about them to use them effectively, and I can (albeit poorly, in retrospect) write them -- but there are so many agonizing subtleties and mindboggling nuances and t's-to-cross and i's-to-dot that I leave the fine art of template crafting to the smart++ folks at Boost <http://www.boost.org/>. Sincerely, --Eljay * in my not-so-humble opinion. I¹m comparing / contrasting C++ template facilities with D¹s code generation mechanism, in particular. It is as-if C++ template mechanism was not designed as a code generation language, and only was realized that it is one long after the fact, and way too late to redesign it.
