Example code

I've been working toward a CSV parser that works efficiently with an input
range. I'm testing it with string and have come to the conclusion there is a
bug in DMD. But I'm having some issue with reducing this code further[1].

The issue manifests itself when I pass a string to a function, which is stored
in a range that produces a range that stores a pointer to the string, which
modifies the dereferenced string pointer.

The pointer is no longer valid by the time popFront is called. A segmentation
fault is produced on line 95 inside countUntil (the string is garbage).
