Urk!  I thought Smalltalk had evolved to the point where blocks were
proper closures... this will definitely bite me as I have many years of
functional programming language intuition, and the subtle distinction
here will certainly lead me astray.  #fixTemps doesn't do what I expect
either.

Is this just Squeak?  Do other Smalltalks get it right?  Are there plans
to fix this in Squeak?
