You can do

for(; !range.empty; range.popFront())
{
    auto e = range.front;
}

without the compiler doing anything at all. But if you want

for(e; range)
{}

you need a way in the language for the compiler to translate that into the 
above. UFCS has nothing to do with it. All UFCS does is take a.b(c, d) and 
make it b(a, c, d).
