In my opinion its even *more* useful than parameterless
functions. In many cases you will use DO to write upgrade scripts or
ad-hoc code.
In both cases its not really much of diference whether you write the
parameter inside the function or outside (as a parameter to it) and
escaping is not a critical part anyway.

So maybe I am missing the point of this discussion?
