OK, so I'm working on some legacy code today when I stumble on a compiler warning: "C4102: unreferenced label". The cogs in my brain started ticking over..."label, label, hmm, what could that be"? Then I took a look at the code. Oh crap. Goto's. In C++. In one function (~100 lines) there were 21 goto calls.
Lucky the author wasn't still with the company otherwise I'd have given him an earful.
Mr Duffy you suck.
