Hi,
I face a problem with variable scoping in block-closures:
arr := Array withAll: #(1 2 3 4 5 ).
blocks := arr collect: [ :i | [Transcript show: i] ].
blocks do:[:item | item value].
This prints 55555 because blocks contains
[Transcript show: i]
for all of its elements and accesses the current value of i.
I would like to have blocks contain
[Transcript show: 1]
[Transcript show: 2]
[Transcript show: 3]
etc.
so it would print 12345
TIA Christoph
