If the input ROR of FrontTransversal consists of empty ranges and the option assumeNotJagged || enforceNotJagged is set, the return value of empty is wrong. === int[][] arr = [[], []]; auto ft = frontTransversal!(TransverseOptions.assumeNotJagged)(arr); foreach(elem; ft) // fails here.. { } === Will Throw a core.exception.AssertError:"Attempting to fetch the front of an empty array of int"
