Indeed. Python is similar, in that it actually would not work in just
sending the buffer or even the region (because interactively, empty
lines terminate a block) - the python mode creates a temporary file in
either case and loads that in the interactive process.

So the semantics are quite regularly not "use the current buffer/region
as input", but rather "update the interactive process with stuff from
the current buffer/file/region in whatever fashion that fits".
