What are the best practices for using C++ templates?

When using C++ templates, it's important to keep your code readable and maintainable. Use clear naming conventions and document your template parameters.

Can you give me an example of a well-structured template?

Sure! Here's a simple example of a template function that swaps two values:

template <typename T>
void swap(T& a, T& b) {
    T temp = a;
    a = b;
    b = temp;
}

What are some common pitfalls to avoid with templates?

Common pitfalls include excessive template specialization, which can lead to code bloat, and not providing clear error messages for template instantiation failures.

How can I improve compile times when using templates?

To improve compile times, consider using the Pimpl idiom, reducing template instantiations, and minimizing the use of complex template metaprogramming.
