Comment #12 on issue 146 by kxepal: Up-to-dated view server
http://code.google.com/p/couchdb-python/issues/detail?id=146

Several questions, could I?
1) what the reason of such wrapper against:
def fun(doc):
   ...
   delta = (datetime.strptime(doc[...]) - datetime.strptime(doc[...])).days
   ...
import datetime

this is not very pythonic to place imports below, but datetime will be  
tried to import only once. However, this style could produce another  
problem: views must have not any state and any dependence from source which  
could be changed later.

2) Hoster could provide 3rd party modules, but it couldn't provide all  
versions of each template engine, for example. May be you needs trunk  
jinja2 with you own patches, who knows? So idea to create fully portable  
pythonic couchapp will be failed.

3) Is preprocessors statements really good idea? I saw them in couchapp,  
but they have been used only for declaration, not within document design  
nor view server.

As intermediate result, this is implementation of require function as is it  
works for javascript view server:

I still need to finish some details, so attachments with new version of  
view server will be later. Sorry, Dirkjan, it seems you to have revise it  
once again, but I'll include documentation for each vital function and more  
tests to make process more easy just(:
