          Issue ID: 22229
           Summary: Struct initialization via constructor missing from
                    language spec
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dlang.org

A struct can be initialized with a value of a different type if it has a constructor that accepts a value of that type:

---
struct S
{
    this(int n) {}
}

S s = 123; // ok: calls constructor
---

However, neither the language spec section on dynamic initialization of structs [1] nor the section on struct constructors [2] mention that constructors can be called with this syntax.
