Hmm, we need to somehow avoid confusing named parameters with positional
parameters. EJBQL (JPA-inspired) has separate notation for named and positional
(not that it is particularly smart .. to me their positional is really named ,
just that the name is a number .. am I wrong?). But I guess in this context we
can treat named as positional, ignoring the name (so e.g. if the same var name
repeats twice, we'd require 2 separate args for the binding). So you are right
again :)
