partial specialization of function template

Question

Can anybody explain why partial specialization is not valid for function template but it\'s fine for class template.

I understand partial specialization might make

Answer 1

Getting confused is enough of a reason, in this case.

And there's an existing alternative solution: overloading. The committee spent a lot of effort (it seems to me, I wasn't there) getting function overload resolution working for templates, and surely part of the reason for that included not having to solve the less-general, hard problem of function template partial specialization.

Answer 2

Now, I'm not an expert but I think the answer to the first part is that partial function specialisation would conflict (and be partially redundant) with function overloading. As for the second part, you can use a template struct that serves as a container for the thing you want to partially specialise.
