For using mixed expressions with different types, run-time polymorphism is required.

does the library need something that runtime-polymorphism delivers and that cannot be done with templates? Not that I'm such a big fan of templates, but they proved useful. Maybe not that much in domain-specific applications, but in interface part of many libraries they work pretty well (Boost is good example here). I'd also argue that they usually proved more extensible than libraries designed around OOP.

Actually pretty useful in domain specific libraries (I guess applications applies too).
