Now I'm using Seaside 3.0 on Squeak 4.1 and the values of the block's temps is set at the point of call (when I evaluate the block) - block are now BlockClosure's. How do I fix the temps to be the values where the block is defined?

Hmm. If we knew whether the closure actually used temps we could implement BlockClosure>>fixTemps as
self hasTemps ifTrue: [
self basicAt: self basicSize put: (self basicAt: self basicSize) copy]
But only the compiler seems to know, not the closure ...
