I do not get why (Yes I know it is because it is not in the syntax.... but it is conceptually not nice). | d | d := Dictionary new. d at: #top at: #below1 put: 1. d at: #top at: #below1 put: 2. d at: #top at: #below1. is not an expression in Pharo. It means that I can manipulate 1 + 3, x + 3 as an expression but not a sequence. So it forces me to use a block to convert artificially a sequence in an expression. [ | d | d := Dictionary new. d at: #top at: #below1 put: 1. d at: #top at: #below1 put: 2. d at: #top at: #below1. ] value So if I want to build a repl executing expression then this is not a Pharo repl but just a stupid expression. I would like to know what would be impact to have sequence and declaration as expression. Stef
