lst.onselect = anonfunc(print(target_item)) What's target_item? If you can't see the signature and see that it's a parameter, you should look externally for it. What are the parameters to an onselect function? Doesn't that seem important enough to see the signature up front? It's not just *how many* arguments are being passed. It's what they're called, too. You cannot interpret the body of a function without knowing that. Hiding that off to the end would make the language worse, not better. Plus, can you name any similar language that does that? Every other language I can think of has the parameters before the body. While this isn't a clinching argument by any means (Python has a different argument order for the ternary if operator, for instance), it's indicative.
