P.P.S. It's not overly hard to write an alternative version of
std.stdio.chunks that returns a real range. Something like this should
do:
// Warning: untested code
auto realChunks(File f, size_t blockSize)
{

Hmm. It's actually not necessary to manually write a foreach loop to
convert an array to an AA. We could, instead, change parseTwoColumnCsv()
