Joris, I'm sorry. I'm still evaluating whether TeXmacs is suitable for 
me yet. Mathematics looks perfect but I don't realize the strength and 
weakness of its interface to e.g. maxima. I have no intention to 
participate actively in TeXmacs development, probably just a couple of 
patches.

As to 'cond' I have no idea. Actually I even don't see the reason to use 
'when' instead of 'if'. It seems 'cond' can not be used withing 
'tree-assign-node!' or at least I can not imagine what should be written 
 in the 'else' clause. That's why an experienced developer must review 
my patches primary to commit.
