This cannot account for an extra 2 seconds. Something else is happening.
Without more of your code, nobody can give a definitive answer except
it is not
supposed to affect it.
The code is here: https://github.com/WebDrake/Dregs/
... and the particular file concerned is
https://github.com/WebDrake/Dregs/blob/master/dregs/codetermine.d
You'll see that there are about 8 different functions in there which
receive as input an array of type Rating!(UserID, ObjectID,
Reputation)[]. These were the inputs I was marking as const.
Hm.. you have marked all your functions pure as well. I don't think this
will affect anything in the current implementation, but it might.
However, I'd expect the opposite (const version is faster) if anything.
