error when std.range.Cycle of static array is a member

[Lutger Blijdestijn]

I'm trying to have a Cycle range of a static array as a struct member, but 
getting a compilation error. Can anybody tell me if I'm doing something 
wrong, or is this a bug?

import std.range;

struct Foo
{
    ubyte[] buf;
    Cycle!(typeof(buf)) cbuf1; // ok

    ubyte[1024] staticBuf;
    Cycle!(typeof(staticBuf)) cbuf2; // error

    void test()
    {
        Cycle!(typeof(staticBuf)) cbuf3;
        cbuf3 = cycle(staticBuf); // ok
    }
}

/std/range.d(228): Error: template instance std.array.front!(ubyte[1024u]) 
incompatible arguments for template instantiation
