The block statements are not necessary unless you want local variables
and then you need "block"
anyway.

I think 

case (
          expr1,   (
                   statement1,
                   statement2
      ),   expr2,   (
                  statement1,
                  statement2
       )
)

looks rather good. I don't like the square brackets. They are not used
as delimiters elsewhere.
