I still think that no scripting functionality should be included here
but only database management (ala sql) functions... Note that
where-statements should be able to cover the same ground as if and
for*...

But I acknowledge that I don't really have much say as long as you're
the one producing the code... :) I might give my way a quick try but
unless it turns out to work out really well with little effort :) I
probably won't produce anything useful... :)

Well, why not... And boolean operators...
