I'll try to answer, but I'm guessing about your assumptions so do ask 
again if I miss.

This is work that is only relevant to the internal Cython compiler, so 
it doesn't compare (or compares very poorly) with LISP. Ie when 
transforming the parse tree one is transforming the input Cython source 
to output C source, but the transform itself doesn't live within that 
parse tree at all.

If what you are asking instead is: How easy is it to write transforms 
compared to writing LISP macros, then the answer is still that it 
compares poorly, but then the goals are rather different too (the number 
of transforms will be max ~30 I think, and the number of LISP programs 
are... :-) )
