This isn't much of a post... except to say how pleased I am with the latest release of Mono (2.10.3). Specifically, F# Interactive (fsi, to friends) finally runs correctly on my MacBook Pro (Snow Leopard). Yay! It no longer throws an exception when you issue the #quit command (or just #q, for the cool kids). Also, it no longer spawns a separate (headless) application just to re-host the GUI message-pump. This was a long-standing pain for me, because it would cause the terminal to lose focus rather abruptly. Of course, I haven't really tested thoroughly to ensure no other issues have appeared. But, as of right now, I'm pleased as punch. Well done, you monkey-loving geniuses!
