Why doesn't "checked" work for sub calls?

[AliRezaGoogle]

Dear Members
Hi,
I have a question:
Why doesn't "checked" work for sub calls? For example consider the
following snippet of code:

checked
{
Overflower();
}

void Overflower()
{
int t=int.MaxValue;
t++;
}

Why Overflower doesn't throw overflow exception?

A fairly complex path could be created if allowed.

Imagine something like this:

public static void Main()
{
checked
{
RunProgram();
}
}

Can you imagine the overhead with this? Ouch!

For example consider the
following snippet of code:
>
checked
{
Overflower();
}
>
void Overflower()
{
int t=int.MaxValue;
t++;
}

Because it is not checked.
