Partial template specialization is a particular form of class template specialization. Usually used in reference to the C++ programming language, it allows the programmer to specialize only some arguments of a class template, as opposed to explicit specialization, where all the template arguments are provided.

In C++, why template function cannot have partial specialization?
Why C++ has this restriction, in other words, if template function could also be partially-specialized, does it lead to any ambiguity or implementation complexity?
Why it cannot act like template class?
