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
