yes i understand that. I try to change some little things in the tex  
and latex language but
  it takes too much time to do that very fine.

arghhhh ... yes \catcode`\:=13 one big error for me  :) and the  
syntax color is very important
  to see this kind of errors !!

Yes with @ we can protect a macro because the user needs to put  
\makeatletter and \makeatother
in his code if  he wants to use @

examples :

the source of latex.ltx or article.cls

\newboolean{@twopt} \setboolean{@twopt}{false}

\newcommand*{\Vertex}[1][]{\@vertex[#1]}%

\Vertex is the command for the user but \@vertex is the macro in the  
package

I use the two ways and a three one (typeit4me) but i really want to  
use esc for things like

newcounter, newcommand
