When the Emacs Lisp interpreter evaluates the body of the while loop, the first thing it does is evaluate the(beginning-of-line) expression and move point to the beginning of the line.
Let me re-emphasize this: when you write code in Emacs Lisp, you do not distinguish between the use of functions written in C and the use of functions written in Emacs Lisp.
The major mode controls which delimiters are signicant, through the syntax table(see Section Syntax Tables in The Emacs Lisp Reference Manual).
The source code, including both the C and Emacs Lisp components, is freely available for examination, modification, and redistribution, under the terms of the GNU General Public License(GPL).
Although the cond special form is not used as often in the Emacs Lisp sources as if, it is used often enough to justify explaining it.
Before learning how to write a function definition in Emacs Lisp, it is useful to spend a little time evaluating various expressions that have already been written.
Emacs Lisp has two primary ways to cause an expression, or a series of expressions, to be evaluated repeatedly: one uses a while loop, and the other uses recursion.
Emacs Lisp can also function as a scripting language, much like the Unix Bourne shell, Perl, Python, scsh, or GNU Guile.
In addition to learning about Emacs as an editor and Emacs Lisp as a programming language, the examples and guided tours will give you an opportunity to get acquainted with Emacs as a Lisp programming environment.
Common Lisp note: Common Lisp has functions union(which avoids duplicate elements) and intersection for set operations, but GNU Emacs Lisp does not have them.
When you type a Lisp expression in GNU Emacs using either Lisp Interaction mode or Emacs Lisp mode, you have available to you several commands to format the Lisp expression so it is easy to read.
However, because errors in C code can easily lead to segmentation violations or to more subtle bugs, which crash the editor, and because writing C code that interacts correctly with the Emacs Lisp garbage collector is error-prone, the number of functions implemented as primitives is kept to a necessary minimum.
To make coding easier, the following bit of Emacs LISP does the'right thing' with bracing, if you want.

And, of course, Emacs Lisp itself.
In Emacs Lisp, point is an integer.
