Ranges, constantly frustrating

[Regan Heath]

Things like this should "just work"..

File input ...

auto range = input.byLine();
while(!range.empty)
{
   range.popFront();
   foreach (i, line; range.take(4))  //Error: cannot infer argument types
   {
     ..etc..
   }
   range.popFront();
}

Tried adding 'int' and 'char[]' or 'auto' .. no dice.

Can someone explain why this fails, and if this is a permanent or  
temporary limitation of D/MD.
