to cause problems it is true, but not bad programming practice :-) ... 
anyhow, this is on the roadmap of uac module, the developer is busy with 
studies and other projects in this period, but if someone will send a 
patch will be accepted.

Seeing your mail from this morning to users@, maybe you should start a 
new dokuwiki page (or a new topic on forum) where to post these 
examples: "Norman Brandinger's examples" or so -- I am sure that they 
will be appreciated by many other users -- and just send small messages 
with links on mailing list to inform the users.

Cheers,
Daniel
