Talk about opaqueness and complexity. With its lack of types, 
declarations and explicit return values scheme is anything but 
transparent to the casual hacker. Add to this the abundance of heavily 
nested parenthesis and result is black-box magic to the uneducated eye.
By the way, in gnetlist.scm I find procedures commented only with:

I don't "stiffen" anything. 
gnetlist already considers symbols with the same refdes to represent the 
same physical device. This is, of course, in accordance with the official 
description of the meaning of redes in the master attribute list. What I 
work on, is to make sure, that the result does not depend on invisible, 
inaccessible subtleties like the order of symbols in the *.sch file. In 
particular  
Such quasi random behavior does not represent flexibility but a bug.

I am unhappy with you implying shortsightedness of about everybody on 
this list, including me. This makes me feel hostile towards your 
opinions.

Not where I am looking at.

So, you propose to work around a bug in the front-end by modification of 
the majority, if not all back-ends.
