Hi
What #fixTemps do is copy the home context.
for example
#(1 2 3) collect: [:each | [each < 3]] collect: [:block | block value]
result is: #(false false false)
you then need a #fixTemps:
#(1 2 3) collect: [:each | [each < 3] fixTemps] collect: [:block |
block value]
result is: #(true true false)
Here the temp call each will exist in 3 different context.
The 3 block [each < 3] will have 3 different parent.
