Sorry, this is a compiler bug, because of the incomplete implementation for the
language enhancement from 2.063.

Code to illustrate issue.

int foo(Range      )(Range    s, in dchar c) { return 1; }  // A
int foo(T, size_t n)(ref T[n] s, in dchar c) { return 2; }  // B

void main()
{
    char[64] buf;

    // Supported from 2.063: (http://dlang.org/changelog#implicitarraycast)
    assert(foo(buf[0..32], '\0') == 2);

    // Not yet supported case (it's a compiler bug)
    assert(foo(buf[], '\0') == 2);
}

In both cases (buf[0..23] and buf[]), the foo calls should match to B, because
it's specialized version to the static array argument than A.
