Problem Statement

Inverted syntax with conditional expressions In traditional syntax conditional expressions are usually shown before the action within a statement or code block: In inverted syntax, the action is listed before the conditional expression in the statement or code block: Inverted syntax with assignment In traditional syntax, assignments are usually expressed with the variable appearing before the expression: In inverted syntax, the expression appears before the variable: Task The task is to demonstrate support for inverted syntax forms within the language by showing both the traditional and inverted forms.

Let's start with the solution:

if (raining==True) needumbrella:=True;
(raining==True) : if (_) needumbrella:=True;

a := 6
6 : a:=_

key.sort(fcn(kv,kv2){kv[0] < kv2[0]}) : listUnzip(_) : 
D.SD((_).xplode()) : return(_);
