void foo(ref string x) { }
void bar(ref int x) { }

void main()
{
    foo("var");
    immutable int x;
    bar(x);
}

test.d(8): Error: function test.foo (ref string x) is not callable using
argument types (string)

test.d(10): Error: function test.bar (ref int x) is not callable using argument
types (immutable(int))
test.d(10): Error: constant 0 is not an lvalue

The error for the 'foo' function should generate two error messages just like
the error for 'bar. 

It could print: 'Error: constant "var" is not an lvalue'. This is especially
useful in templated functions.

Or maybe better, generate a single error message in both cases, something like:

test.d(10): Error: function test.bar (ref int x) is not callable using argument
types (immutable(int)), constant 0 is not an lvalue.
