Bug 9984 – inout qualifier is skipped for constructor arguments (template constructor only)

The following code does not compile: -------------------- struct Foo { int[] p; inout this()(inout int[] a) // test.d(5) { p = a; } auto foo() inout { return inout(Foo)(p); // test.d(12) } } void main() {} -------------------- test.d(12): Error: template test.Foo.__ctor does not match any function template declaration. Candidates are: test.d(5): test.Foo.__ctor()(int[] a) test.d(12): Error: template test.Foo.__ctor()(int[] a) cannot deduce template function from argument types !()(inout(int[])) inout -------------------- There is no error if constructor is function not template
