Creating a function pointer to a ref function can only be done using auto, but by no explicit means. Also, aliasing a ref function pointer to another type can't be done.

Example code showing the issue:

int x;
ref int foo()
{
    return x;
}

void main()
{
    auto func = &foo;
    pragma(msg, typeof(func).stringof); // outputs "int function() ref"
    //int function() ref func; // uncomment for error
    func() = 5;
}

Error when auto is not used:

testreffuncptr.d(9): no identifier for declarator int function()
testreffuncptr.d(9): semicolon expected, not 'ref'
testreffuncptr.d(9): found 'ref' instead of statement
