Varargs Record Patterns, Literal Record Patterns and Let Expressions vs Member Patterns

[Brian Goetz]

I think you may have fallen into an "either/or" trap.  Varargs patterns 
and constant patterns are already on the road map; we experimented with 
an imperative match (let), and found that the obvious interpretation has 
some challenges.  But in any case, these are all part of the story, and 
we don't have to pit one feature against another as the "winner".
