Here a quote from a current thread into wikitech-l.

Using #lst to implement variables into wikitext is really "a terrible hack" in your opinion too...? If it is, I feel myself really uncomfortable and depressed... :-( 
I'd like a clear statement about, and - if needed - clearly stated limits in the use of #lst (that IMHO is implicitely something that "implements named variables" into wikitext, simply calling those variables "named sections")

Using #lst to implement variables in wikitext sounds like a terribl 
hack, similar to how using {{padleft:}} to implement string functions
in wikitext is a terrible hack.

Thanks Roan, your statement sound very alarming for me; I'll open a specific thread about into wikisource-l quoting this talk. I'm doing any efford to avoid server/history overload, since I know that I am using a free service (I just fixed {{loop}} template to optimize it into it.source, at my best...) and if you are right, I've to change deeply my approach to #lst.
