We discussed this in the core team meeting today.  Consensus seems to be that a change needs to be made to regain syntactic convenience here.  Discussion was leaning towards allowing (at least) the parenthesized form, but more discussion is needed.


One (tangential) thing that came up is that tuple element names in tuple *patterns* should probably be deprecated and removed at some point.  Without looking, what variables does this declare?:

	let (a : Int, b : Float) = foo()

?
