`.byChunk` caches and `.joiner` hides this caching mechanism. 
Both operations happen under the hood "incrementally" while using 
the final input range because of lazy evaluation, so if your file 
is big, you are assured that only slices of N bytes (1024 in my 
example) will be loaded at once in the DRAM (unless you 
accumulate the whole thing later). This matches well to a "file 
stream concept", at least to read.

But as said in Jonathan M Davis's answer you can also read the 
whole file in a string or a ubyte[].

Yes but this is a bit like this that phobos ranges and algorithms 
work. You have many independant low-level blocks with which you 
can compose rather than big classes that wrap everything. The 
whole standard library is organized around this.

std.stream was not compliant with this system and this is why 
"they" deprecated it (at least this is how I understood this).
