	Well, Python itself doesn't handle "out" parameters... The win32
extensions mostly access the defined Win32 API... May not be that useful
for ad-hoc interfaces.

	The ctypes library may be a more direct means -- it interfaces
between Python objects (with specific attributes/properties) used as
data types and the C-language calling conventions... "ctypes exports the
byref() function which is used to pass parameters by reference"

	PowerShell likely uses the same method you'd need in Python --
passing a mutable object (an array in PS), but the receiver would need
to be expecting such an object.
