I think that GOTOs have nothing to do with OO programming, but instead 
they relate to "structured programming".
In C and Pascal (and many many others), which are structured, you can 
totally avoid GOTOs, if you want. But, as Nando says, sometimes GOTOs 
are clearer that while-do-loop-if-elseif-elseif and so on.
The real thing is to have *both* structures and GOTOs; if either is 
missing, then the language is poor.
