This is true for simple flow control. However, when you had to break out of
multiple levels, or continue not the inner loop, but the middle loop, the
use of extra booleans sure made the code less understandable than a 'goto'
a label that stood in for that purpose... This was something that wasn't
well understood by language designers, and even today C and C++ neither
have good flow control beyond the basics. Even though both break and
continue could take an optional count without breaking old code....
