13:28 mithos28: I am trying to deal with unsafe operations for flonums, and it turns out that flround and unsafe-flround are free-identifier=?. Am I wrong in thinking that these should be different bindings even if they are the same value?
13:30 jonrafkind: well what do you care
13:30 mithos28: I am going through typed/racket base types and removing duplicates
13:30 mithos28: so I added a check to see if the binding is already in the map
13:31 mithos28: in the future these two identifiers could have different bindings, so the source code should have both of them there
13:32 (quit) MayDaniel: Read error: Connection reset by peer
13:32 mithos28: but if they are the same binding, I cannot tell it from an extraneous duplicate in the source code
13:34 jonrafkind: where do those bindings come from?
13:34 jonrafkind: oh racket/flonum
13:34 mithos28: I am getting them from racket/flonum and racket/unsafe/ops
13:35 jonrafkind: i wonder if thats a bug actually
13:36 jonrafkind: racket/unsafe/ops provides all its stuff with a prefix of unsafe-
13:36 jonrafkind: but racket/flonum doesnt provide unsafe-flround as flround, it just provides flround directly
13:36 jonrafkind: so how is racket/flonum getting flround..
13:37 (join) masm
13:37 mithos28: racket/unsafe/ops just prefix-outs the #flfxnum exports
13:38 mithos28: and so does racket/flonum
13:39 mithos28: so they are both the same binding provided by the #flfxnum primitive module.
13:40 jonrafkind: ah right flfxnum
13:44 mithos28: so do you think that this is working as intended?
13:45 jonrafkind: yea
13:46 jonrafkind: i guess you just have to know that flround is the same thing as unsafe-flround
13:46 jonrafkind: if you only consider flround and someone passes in unsafe-flround everything will work out
13:46 jonrafkind: so you should be able to remove one of them if you are eliminating duplicates
13:47 mithos28: I think the plan will be to comment out the unsafe ones with a mention of why
13:47 mithos28: so that if it is it changed later
13:47 jonrafkind: whats the issue in leaving them both in?
13:47 mithos28: the duplicate checking code is run at runtime
13:48 mithos28: so it will fail if there are duplicates
