My reasoning so far is that the best way to do this is:
Step 1: parse a view.html file to extract the python code between "{{" and
"}}" and output it to a file view.html.py where "{{" and "}}" are replaced
with comments like:
#1
if bla:
#/1
#2
pass
#/2
Step 2: create a view3.html where "{{" and "}}" are replaced with #1 and
#/1, next ones with #2 and #/2, etc
Step 3: properly format the view.html.py file, and this something I don't
know how to do, but clearly web2py does so that the code is properly
interpreted
Step 4: run 2to3 over that file
Step 5: compose a new view.html by parsing view3.html replacing code
between the first #1 and #/1 with the new (2to3 generated) code of
view.html.py between #1 and #/1
