--- Comment #3 from Iain Buclaw <ibuclaw at gdcproject.org> ---
Possibly reduced test:
---
template binaryFun(alias fun)
{
    alias binaryFun = fun;
}

struct ChunkByImpl(alias pred, Range)
{
    alias eq = binaryFun!((a, b) => pred(a));
    Range r;
    this(Range )
    {
        eq(r, r);
    }
}

auto chunkBy(alias pred, Range)(Range)
{
    ChunkByImpl!(pred, Range);
}

void main()
{
    auto n = 3;
    1.chunkBy!(a => a+n);
}
