Detailed Description

Represents a C++ deduction guide declaration.

template<typename T> struct A { A(); A(T); };
A() -> A<int>;
const FunctionProtoType * T

In this example, there will be an explicit deduction guide from the second line, and implicit deduction guide templates synthesized from the constructors of A.
