Eelco Dolstra 4a5042a1a1 * Python recompiles a Python if the mtime stored *in* the pyc/pyo file
differs from the mtime of the source file.  This doesn't work in Nix
  because Nix changes the mtime of files in the Nix store to 1.  So
  treat that as a special case.

  Yes, this should make Python programs faster.

Python is a remarkably powerful dynamic programming language that
is used in a wide variety of application domains. Some of its key
distinguishing features include: clear, readable syntax; strong
introspection capabilities; intuitive object orientation; natural
expression of procedural code; full modularity, supporting
hierarchical packages; exception-based error handling; and very
high level dynamic data types.
