Sometimes it is helpful to provide info, and too often people have
misunderstanding and need explanation. Emacs is full of terms,
concepts, definitions which cause misunderstandings. If that would not
be so, I would be very happy, though it is.

You must know that there are different types of readers, different
audience. Emacs Lisp manual is written in technical manner, it wasn't
written in manner of a tutorial.

Imagine people in need of tutorial reading just this sentence:

11.7.1 Explicit Nonlocal Exits: ‘catch’ and ‘throw’

Even if not a beginner, experienced programmer could mix those terms
with something else.

Unspoken of the rest of the article:

"Most control constructs affect only the flow of control within the
construct itself. " -- what level of programming person must already
have to undersand only this first sentence? Reader must already have
basic programming knowledge, control structure understanding, scope
awareness, etc. 

If person is not on the level to easily understand just the first
sentence, mind gets blocked, misunderstood words create blanks in the
mind, and people stop using it, and it is good thing that Heime or
other people do not give up, but ask for answers here.
