Maybe related to issue 7661

I think the assignment at line 5 has to be valid, because int[1] is a value
that gets copied to another immutable value:


int[1] foo() {
    return [1];
}
void bar(F)(F fun) {
    immutable x = fun(); // line 5
}
void main() {
    bar(&foo); // line 8
}


test.d(5): Error: cannot implicitly convert expression ((*fun)()) of type
int[1u] to immutable(int)[]
test.d(8): Error: template instance test.bar!(int[1u] function()) error
instantiating
