Why wouldn't you instead write:

void foo() throws Exception // shut up compiler
{
    functionWithException();
}

That's easier, and no worse than C# even though you have defeated 
checked exceptions.

Here's the point: with checked exceptions good programmers can 
write good code. Without checked exceptions even good programmers 
are forced to write bad code. It is impossible to prevent bad 
programmers from writing bad code, so that should not even be a 
goal, but enabling good programmers to write good code should be 
a goal.
