class C
{
this() inout { }
this(inout int[]) inout { }
}
void main()
{
auto c0 = new immutable C(cast(immutable int[]) null); // OK
auto c1 = new immutable C(); // Error (line 10)
auto c2 = new immutable C(null); // Error (line 11)
}
---
dmd output:
---
main.d(10): Error: inout constructor main.C.this creates inout object, not
immutable
main.d(11): Error: inout constructor main.C.this creates mutable object, not
immutable
---
Partial workaround:
Mark constructor as `pure` or `immutable` if possible.
