Nice! I don't have experience with memory-mapped files. What are
the pros and cons?

Good idea. Good reason to have it in std.file. There might

Good idea. Good reason to have it in std.file. There might also
be platform dependent shortcuts?

Binary comparison is easy. Just read the files by fixed-sized

Follow up question... What is the best @safe way? Since
File.byChunk() is @system. Just out of curiosity, I would rather
use it and flag my code

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)
{
static struct Result

Why it is not
It's not easy to do by hand of course, but I was wondering if
there was one simple function taking two file names and just
returning a bool or something like that. I haven't found it in
std.file.
If such a function doesn't exist in Phobos but there's a good
implementation in some other librar
