Does anyone like my minimalistic simplistic syntax here? You don't need to include a header file nor write lambda syntax. Perhaps we could also make use of the 'throw' keyword to indicate how the scope was exited:

void Func(void)

{

    Handle h = GetResource("monkey");

    if ( ! h ) return;

    ~ { if throw FreeDevice(h); } 

    // The rest of the function goes here

}

In the above code snippet, FreeDevice only gets called if Func is exited by means of a thrown exception. The two keywords 'if throw' side by side would have a special meaning here.
