RE: [Python] Allow attribute references to gdb.Value objects
That's a fair point, but it comes at the expense of making the code look rather un-Pythonic. It seems reasonable to offer the option, and document the fact that code that takes advantage of it may be affected by new built-in attributes.

We considered this initially, but decided on the current approach instead. The current approach lets us add attributes to Value without breaking any existing code.
