// Illustrates a (now fixed) bug where mutation altering a
|
|
// subscription caused the `retracted` half of a during instance to be
|
|
// lost.
|
|
//
|
|
// Symptomatic output:
|
|
// x= 123 v= 999
|
|
// x= 124 v= 999
|
|
//
|
|
// Correct output:
|
|
// x= 123 v= 999
|
|
// finally for x= 124 v= 999
|
|
// x= 124 v= 999
|
|
//
|
|
// Should eventually be turned into some kind of test case.
