Well, I've been home for a few days now. I still haven't fully unpacked (and I probably never will).
I started working on some type-reading code in gnome-debug. This a) speeds up variable viewing b) fixes a problem I was having when an expression changed types (for example when a stack frame changed) and c) lets the user look at a variable's type.
As a break from the variable-viewing code, I spent a few minutes starting to write support for attaching to processes. I figure I'll finish that up tomorrow.
