Yes, goto is the C programmer's exception handling. Describing the 
exception scenario with additional scopes seems not only less elegant,
but also wrong from a design perspective.

Yes, I think the rule should be "use goto if you really think you mess
up your code otherwise, and await the code review to rend your
implementation"
