to be exact. Reading it you can tell exactly how much of an
mathematician Dijkstra really was. At these times It's best to keep in
mind a quote:

"I used to understand the Theory of Relativity, but then the
mathematicians got hold of it."

Well, in the formentioned paper he made the case that while - do, and
do-while are superfluous; we should all use recursion instead.
Out of respect of the dead, I'm not going to say what I think of that.

Since C don't allow goto beyond it's function, most of what was
problematic of goto's aren't legal anyway.
But I submit that those that think goto's are evil never had to deal
with smp locks.

Most goto's I've seen deal with error handling, and I guess much could
be "solved/hidden" with a "on_return { };" clause, but...
An on_return would be a simplified try/trow/catch that is limited to the
IMHO: a trow that is catch'ed somewhere up the call stack, is just as
much an evil as goto.

Considering that students are bottled on Java these day, they're still
learning a language unusable for real work.
