thank you for your= opinion.

i have one more question.

=
static object is always static and binding in that?
wi= ll that have to free timing?
where is this?

<= div>i think non free static object is out way the lifecycle theory.
lifecycle is halting promise.
if you can not break the old gar= bege.so you hate it.
halting=C2=A0 promise is clear the that prob= lem.yes!

and the finalizer is solve it.so i think.=

Static objects are no dif= ferent from dynamic objects in this regard. If you need to call a static me= thod you can create a scoped object and call it inside of the destructor li= ke you would do inside a finally segment.
The advantage of not ha= ving a finally is that you don't need to indent with a try block just f= or the sake of it:

try
{
=C2= =A0=C2=A0 // code
}
finally
{
= =C2=A0=C2=A0 // all the indentations here are useless noise needed because = we want a finally block
}


<= /div>
There is also a proposal to standardize such scope guards: h= ttp://www.open-std.org/jtc1/sc22/wg21/docs/papers/2018/p0052r9.pdf
