I'm wondering if continuations (or continuations + set_trace_func to 
catch the method end) could be used to achieve that, but am not a whiz 
at callcc, and am up past my bedtime (hence am not going to experiment 
w/ it).

Is there a Weirich in the house?

(Even if it can be implemented using such hackery, I might consider that 
a smell that it's so different, and doesn't map to Ruby's ways, and be 
hesitant to use such a beast in GP code.)
