Well, it doesn't necessarily have to be 'as'. It could be
 def Fred = namedtuple('x y z')
but that wouldn't give as much of a clue that something
special is happening in the middle.
Is the reversal really all that much of a problem? It makes
sense when you read it as an English sentence: "Define
Fred as a named tuple." Just like all the other uses of
"as" mean what they seem to mean.
Given that each existing use of 'as' has its own unique
quirks, forcing 'as' to always bind on the right regardless
of anything else might be seen as a foolish consistency.
