simple it is, and the fact that it doesn't use leading tabs the way that make
does. It is intended to be the assembler for higher-level build systems which
are more like compilers. I personally use it as a make replacement because it
does what I tell it to do, and nothing else. It may fit what you're after.

Ideally, the memory is owned by the side that created it, with the other side

u're suddenly surprised by Py2 starting up when you've been using a Py3
interactive interpreter. For me, I'd probably give my students a block of code
that they are asked to copy at the start of their files to test for Py2 or Py3,
and to raise an exception on Py2. After that, I just wouldn't worry about it.
