Good point.

For now, it seems like three choices are available (for the isinstance
check):
1) the "butt ugly" mechanism,
2) the "type-method spelled backwards" mechanism,
3) the "import types / heavy artillery" mechanism,
(<wink>s throughout)

Python 2.2a1 (#21, Jul 18 2001, 04:25:46) [MSC 32 bit (Intel)] on win32
Type "copyright", "credits" or "license" for more information.

Don't know if there are any plans/thoughts regarding the addition of a
"module" or "mod" equivalent of "int" (etc.) someday.
