my favourite for streaming a file:

Is this an efficient way of reading this type of file? What
should one keep in mind when choosing chunkSize?
reasonably efficient, yes. See http://stackoverflow.com/a/237495
for a discussion of chunk sizing when streaming a file.
It provides you only one char at a time instead of a whole
line. It will be quite constraining for your code if not
mind-bending.

File(fileName).byChunk(chunkSize).map!"cast(char[])a".joiner().lineSplitter()
