In what way is that different from using an ordinary lambda
function?  i.e.:

def _converter(scale):
    return lambda arg: scale * arg

Of course, the use of lambda functions is very limited
because (unfortunately) they can contain only one single
expression.  But other than that, it's pretty much the
same concept, isn't it?

Best regards
