Not really. My life just became extremely busy and seems like it will  
be until then end of the month.

It's the same darn bug, with "ensureNamespace: #Cairo" not being  
explicitly prefixed by the lobby. I've pushed a patch for it.

Mostly, I suggest grep'ing. Introspection methods in the image are  
available to find compiled-methods from which you can get their  
sourceTrees, but those have comments stripped and macros expanded.  
Basically there is no source database in Slate yet, so it's simplest  
to grep src/ or src/lib/ or src/mobius/.

Example:
Slate> #compareAndHashUsingSlots: findOn: {Root. NoRole}.
[compareAndHashUsingSlots:]
Slate> #compareAndHashUsingSlots: implementations &in: prototypes.
{"Set" [compareAndHashUsingSlots:]}

Thanks. There may be some useful work on the performance issue soon,  
which should help and maybe will draw Todd back in as well.
