Maybe I'm grumpy this morning (though I felt the same reading this yesterday).
-1 for any names commencing with __ (or even _).
-1 for new globals.
-1 because I can imagine wanting different nuances on the definitions
above; in particular for DIR I can well imagine wanting bare
dirname(abspath(FILE)) - semanticly different to your construction.
There's lots of scope for bikeshedding here.
-1 because this is trivial trival code.
-1 because you can do all this with relative paths anyway, no need for abspath
-1 because I can imagine being unable to compute abspath in certain
circumstances ( certainly on older UNIX systems you could be
inside a directory without sufficient privileges to walk back
up the tree for getcwd and its equivalents )
-0 for adding some kind of convenience functions to importlib(?) for this
(+0 except that I can see heaps of bikeshedding)
