But it's nice to have.

In the lecture "Introduction of Computer Science 2" we had to learn 
functional programming with the programming language OCaml. There we 
used tail recursion a lot (and I always tried to write my functions in a 
tail recursive form) and it's nice to see/know that FPC can do that as 
well. :)

Btw: is this a CPU dependent optimization?
