We have presented examples before where present LaTeX syntax 
is not nice, and this still is my opinion.

A better proposal than using different category codes is 
programming macros with optional arguments obeying 
a convention that makes a choice of delimiters available to users.  
Any macro package replacing \@ifnextchar[ by some 
\ifx\let@token\opt@arg@delim could be run this way. 

If no LaTeXY will adopt this, I will call it LüTeX :-)

Cheers, 

    Uwe.
