 # This function now implements Python byte-compilation in three different ways:
 # Python >= 3.4 and < 3.9 uses a new module compileall2 - https://github.com/fedora-python/compileall2
+# In Python >= 3.9, compileall2 was merged back to standard library (compileall) so we can use it directly again.
 # Python < 3.4 (inc. Python 2) uses compileall module from stdlib with some hacks
+
 # When we drop support for Python 2, we'd be able to use all compileall2 features like:
 # - -s and -p options to manipulate with a path baked into pyc files instead of $real_libdir
 # - removed useless $depth - both compileall and compileall2 are limited by sys.getrecursionlimit()
 # These changes will make this script much simpler
-# In Python >= 3.9, compileall2 was merged back to standard library (compileall) so we can use it directly again.
