A template defined in a module interface is instantiated in the importing unit, where its body's types must be complete. A declaration reaching the importer only through the interface's global module fragment is not enough for MSVC: cParser::operator>> uses std::stringstream, and every unit that parsed a float got an incomplete type. 526 headers across 161 units, derived from what each interface's template bodies actually name.
