I do agree for e.g. with binary data some data can't be read with

you need to read small chunks of varying size),
I don't see why that should be true.
How do you tell front and popFront how many bytes to read?
std.byLine() does it.
Have you looked at how std.byLine works? It certainly does not use a
range interface as a source.
In general, you can read n bytes by calling empty, front, and popFront n
times.
I hope you are not serious! This will make D *the worst performing* i/o
language.
This should be evidence enough:
