And while I like the result, I got bogged down converting things, so I thought I'd send some initial work, with the idea that if this looks good, other code can be transformed in pieces. Since this is extracted from a larger series, there is some code in here that isn't currently used in-tree. This is mainly true for the gdb functions that wrap Python APIs, see patch 2. Patch 4 shows what the end effect is, but the patch is somewhat hard to read IMO. So for instance now the 'title' getter for a TUI window is just an ordinary method: const std::string & gdbpy_tui_window::title () { require_valid (); return window->title (); } Since it wants to only operate on a valid window, require_valid will throw if that isn't the case. Note there's no explicit error checking, no casts, no messing with reference counts, and the return type is just a string. All these boilerplate details are handled by a template wrapper function.
