I read the article as saying it ignores all upper-bounds, and 4.0 is just an example. I could be wrong though - it seems ambiguous to me.

But if we accept that it currently ignores any upper-bounds checks greater than v3, that's interesting. Does that imply that once Python 4 is available, uv will slow down due to needing to actually run those checks?

He's calculating EV above cost. If you look at the calculation, the first term is -1000 to account for the initial investment. So the final value is tell you that you got back the initial money plus 900 more.

I was not trolling, I actually dislike MongoDB aggregation syntax and it seems like PRQL is something that could potentially replace it or go on top. Admittedly I only took a quick glance at PRQL though, so perhaps I misunderstood something or it's not applicable to this case.

There are examples on Mongo's page, eg https://www.mongodb.com/docs/manual/core/aggregation-pipelin...

eg:

  db.orders.aggregate( [
   // Stage 1: Filter pizza order documents by pizza size
   {
      $match: { size: "medium" }
   },
   // Stage 2: Group remaining documents by pizza name and calculate total quantity
   {
      $group: { _id: "$name", totalQuantity: { $sum: "$quantity" } }
   }
  ] )

Having spent more time in MongoDB aggregations than I'd like to lately, I really wish they'd support this. So much more sensible than the madness they've got going on.
