It's in MSDN (the version that came with VC++6) under
"Internet tools: platform SDK"; not in the Contents, but
easy to find under Index or Search.

You can do that with plain old IDispatch.  With Microsoft's
ScriptControl, you can load scripts into any ActiveScripting
compatible language (Python should qualify), ask for the
CodeObject of a module, and it should have the dynamic
qualities you require.

Actually, what appear as properties are variables, as in
the example you quote:

> objPerl.EvalScript '$greet = 'Hello, world.\n';"

See?  "$greet" is a _variable_...

Yep, because it's a variable in the script.
