I agree on all points, although I'm a bit sceptic about using "normal"
characters like ';' as a syntax specifier (even they are rearly used).

I would recomend to expand at to 1/10 of seconds right away. Otherwise you
will soon start to be backward-compatible to something no one really wants.

It is a good idea to make it logic for the user right away. It is much more
work, but very often is it more extendable. If you always try to think how you
would like to have something if you were a user then it really gets better.

Maybe I will have to construct some kind of parameter like '%{...}' that can
make wps-lines more readable...

Yep, I totally agree. So if you don't make it user-friendly then you are
joining the group :-)
