int array[i in set1] = ((sum(j in set2) 1 >= 1) ? 1:0);that is, the two “i” on either side of the “equal” sign = are not linked. This is called scopehiding because the second “i” hides the first one in a nested scope.In contrast, this statementint array[ in set1] = ((sum( in set2) 1 >= 1) ? 1:0);codes implicit slicing, which is equivalent to:int array[i in set1] = ((sum(j in set2 : j==i) 1 >= 1) ? 1:0);In other words, there is no implicit slicing outside tuple patterns.See also Modeling tips in the Language User’s Manual.I L O G O P L D E V E L O P M E N T S T U D I O L A N G U A G ER E F E R E N C E M A N U A L139
