No because the a..b syntax is not a D language construct that we can use 
anywhere that it makes sense. It only works as number ranges inside 
foreach loops, when indexing slices, and case value ranges.

Also no, because there is no equivalent of F#'s -> syntax, we have to 
use map.

I am waiting to see a language solution that does not use even sin(). :o)
