Jeremy, Stobot,
Any method that can make wikify behave better would be appreciated.
Jeremy, can you give an example of this please

Stobot,
- I think your pattern could be of great use, pending a better method if
you could publish your code pattern with some examples It would be a good
contribution and others may also show alternative ways to achieve the same
thing.
- There are a few cases where construction of filters before use would
get around other limitations or the need for nested filters.
- I am also starting to configure some longer filters as global macros
such as standard-fields so they can be excluded from the result of the
fields[] operator.
