Issue ID: 19618
Summary: Incorrect conversion of function returning
`typeof(null)` to function returning an associative
array
Product: D
Version: D2
Hardware: x86
OS: All
Status: NEW
Severity: regression
Priority: P1

Fix for issue 8589 was incomplete.
---
void f(int[int] function() del)
{
assert(!del());
}
typeof(null) g() { return null; }
void main()
{
f(&g);
f(() => null);
}
---
As typeof(null) is a pointer type, whilst associative arrays are value types.
So can't possibly be covariant.
