Actually, the problem has been fixed in git HEAD, it's just that 2.063
doesn't have the fix. The basic cause is that std.range.chunks in 2.063
and earlier requires slicing, but I need to use it with a forward range
that doesn't have slicing. This limitation has been removed in git HEAD
(upcoming 2.064).

I've already solved the problem in the code by using "static if
(__VERSION__ < 2064L)" and providing a bare-bones replacement of
std.range.chunks that does support forward ranges.
