It is not an overloadable operator, but it absolutely is an operator; it has operands, it has operator precedence, it has associativity, it is documented as an operator, parsed as an operator and codegenned as an operator. For a sequence of length length, ^n points to the element with offset length - n from the start of a .
Then, If the return type of the selected operator is implicitly convertible to the type of x, the operation is evaluated as x = x op y, except that x is evaluated only once. The >> operator shifts x right by an amount specified by y. So in the assignment statement , the variable y is assigned with the value “100“.
