Yes, it is a very unusual use of a command I have to admit, but I use  
it 'comment out' parts that I want there, but not deleted, in case I  
want them in later on. I just define a command at the beginning:
\newcommand{\comment}[1]{}
so that it is all omitted out, but if I want it there I'll just  
change the command to read:
\newcommand{\comment}[1]{#1}

So, our problem in general is that, inside LaTeX code, we want to  
allow patterns that appear in the TeX syntax, but in such a way that  
they understand that they have LaTeX power, i.e. that they can  
recognize anything in the LaTeX syntax, not just the TeX syntax. Not  
sure if this is possible as things are right now.
I don't think it would be correct to include the LaTeX syntax in TeX  
either, since if the file is an actual TeX-file and not a LaTeX-file  
there shouldn't be LaTeX code in it. Not sure what the right way to  
structure things is. I do like the idea of TeX commands being in  
their own syntax file, and the other syntaxes inheriting from them,  
but I am not sure what the best way to implement this would be then.
For now I am happy with things being the way they are. This problem  
doesn't really appear in most regular uses of the bundle.
