massimo,
filters... ok but what if I need to make more operations with strings
etc, python operations, imports, parsing something ?
More lines of code.
For example I need to operate on dictionaries ( defining new, parsing
etc )
Theoretically, I can apply filters on controller side... but then
there is one ( or more ) loop more.
