The 'this' may be destroyed at the time the lambda is executed.
consider the following async pseudo code:
---
try {
await func1A();
func1B();
} catch() {
error1();
}
try {
await func2A();
func2B();
} catch() {
error2();
}
---
transcompiled to Promise chain:
---
func1A.then([](){
func1B();
})
.fail([](){
error1();
})
.finally([](){
return func2A();
})
.then([](){
func2B();
)}
.fail([](){
error2();
})
---
a previous promise has been rejected.
Example:
----------------
int result = 0;
try {
result = await funcA();
} catch() {
result = await funcB();
}
funcC(result);
----------------
Can be translated to:
---------------
funcA()
.failCatch([](){
return funcB();
})
.then([](int result){
funcC(result);
})
