Really? "haystack" and "needle" are taken from the proverb (and used in
the PHP docs). But if you like this more no problem:

if.c = function:inList
if.c.value = l
if.c.list = w,o,r,d

There is no "and" in this example.

Tastes differ.

I want to write an expression directly in Typoscript where it belongs
to. TS sser functions are nice to have, but if I can I try a TS solution.

I got it now that you and Joey like the natural language approach.
Ernesto and me favour the formal logic approach.
