I was originally suggesting that there are some powerful concepts in
various languages and other paradigms that transfer very awkwardly
or not at all into the C language.  While I do not believe that programmers
who work with C are necessarily hackers, I would maintain that without
significant exposure to other languages they will unknowingly be locked
into a poverty of expression.

That particular Pascal feature can of course be abused just like any other.
But if you have done some functional programming and made use of function
parameters and curried functions, you will find it possible to design some
tasks according to that paradigm and use the local functions to simulate
currying.

If that's not your cup of tea, then don't bother.  But the point remains: a
powerful concept is directly provided by some languages and supportable in
others.  But not C.
