I've had the need to read and save an array element just before updating it to a new value:
oldValue= array[index]; array[index]= newValue; doSomethingWith(oldValue) If instead I had had to post-increment/decrement it I could have written just : doSomethingWith( array[index]++ ); which is shorter, clearer, and does not need any temp. var. So, my question/idea/proposal (I hope it's not too dumb) is, why not to create a "post-assignment" operator ? One that given the expression: `aReference *postAssignmentOperator* newValue` would assign newValue to aReference but would return the value that it had before the assignment. doSomethingWith( array[index] := newValue ); It may serve too to swap(a, b) : a= ( b:= a ) ? -- Jorge. _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
