How about a change to R7RS + SRFI? That would free TM from any particular 
Scheme implementation. How many non-(quasi-)standard features (of Guile 1.8) 
does TeXmacs currently use? Which ones are the most relevant ones that 
prevent an easy move to „Standard“ Scheme? (Pandora box question: what about 
a reimplementation in Common Lisp? There is not only a big super-stable 
standard, but nowadays, via Quicklisp, also a large number of compatible 
libraries.)
