Hi,

I don't think that #fixTemps should fix the problem:

The to:do: block is create once but #fixTemps copy the home context
This copy change the semantic scope of i.

=> Even with full closure your code would not work without #fixTemps.

An other solution is to use curification:

	stuff := #(foo bar).
	results := OrderedCollection new.
	1 to: 2 do:[:i|
		results add: ([:show | [Transcript cr; nextPutAll: show;flush]]  
value: (stuff at: i))
	].
	results do:[:e| e value].

This work with full closure but don't work with squeak block. So you  
still need a #fixTemps if you are not using full closure:

	stuff := #(foo bar).
	results := OrderedCollection new.
	1 to: 2 do:[:i|
		results add: ([:show | [Transcript cr; nextPutAll: show;flush]]  
fixTemps value: (stuff at: i))
	].
	results do:[:e| e value].

Cheers
