	I'd suspect not -- if that "Unix expression" really means a SHELL
expression...

	The command shell is responsible for translating the ~ into whatever
it represents (home directory?).

	Inside a Python script, you'll need to use the os.environ module to
retrieve the environment variable that represents the same information,
and join them yourself.

infile = open(os.path.join(os.environ["HOME"], "prog/.../...test"), "r")
