This is the CTFE problem on out of function scope.

struct G {}
struct F(T) { void f(ref T) {} }

pragma(msg, F!G().f(G.init));   // ICE
enum b = { F!G().f(G.init); return true; }();    // OK

void main()
{
    F!G().f(G.init);    // OK
}

Before CTFE begins, the code in comment 1 is translated into:

F().f((G __tmpsl5 = G(); , __tmpsl5))

The problem is that the comma expression is evaluated outside of CTFE.
This would be fixed by bug 7988.

I get the following message from 2.064 head:

test.d(3): Error: function test.F!(G).F.f (ref G _param_0) is not callable
using argument types (G)
test.d(3):        while evaluating pragma(msg, F().f(G()))

No ice.
