It seems that the compiler fails to infer the type of an anonymous function
if the function contains more than one statement. For example, this works:
let a = [[1,2],[3],[4,5,6]]
var b: [Int]
b = a.flatMap { elem in
return elem
}
But this fails with an error "cannot convert return expression of
ed anything here -- this is my
recollection of listening in on various discussions in the past).
