Numerical values are less important than S_ISxxx() macros. Example:
   #define      S_ISDOOR(mode)  (((mode)&0xF000) == 0xd000)
0xd000 is (stat.S_IFSOCK + stat.S_IFIFO).

And how do you represent the file mode with enums? I don't think that
enum should be used in the stat module.

I would prefer a stat object with methods than having to calls
low-level functions. Something like:

The idea was discussed in http://bugs.python.org/issue11406 to solve a
real API design issue. How should os.scandir() return the "is a
directory" information with a portable API.

I'm not saying that stat.S_ISREG should go away. The two approaches
are complementary.
