DIP Draft Reviews

[Mike Parker via Digitalmars-d-announce]

I'm getting ready to start prepping one of the DIPs in the PR 
queue for community review. It proposes adding an `in` operator 
for arrays. I haven't gone through it in detail yet, so I invite 
anyone with time on their hands to provide feedback on the Draft 
so we can more speedily get in shape to kick off the big-league 
reviews.

While you're at it, feel free to poke around and leave some 
feedback on other drafts in the queue.
