It's possible that typed classes are slowing down typechecking, in particular typechecking methods can be slow. (I think this is in part because Typed Racket has to fold over entire types, and class types can be large) The typechecker for classes actually has some performance logging (that's disabled by default): https://github.com/racket/typed-racket/blob/master/typed-racket-lib/typed-racket/typecheck/check-class-unit.rkt#L37 which you could try turning on to see what's slow. (you will have to capture the log output, e.g., by setting the PLTSTDERR environment variable) Also if you send me some self-contained code that's particularly slow to typecheck I can look into it too. We don't have a global flag to turn off typechecking right now. I think the best thing for us to do is to try to make TR faster.

But now I cannot reproduce it in the real world code either, just like that it appeared unreasonably. Let me see if it would show up again. And here is another question. Developing GUI Application involves typed class system heavily, which makes the compiling time terribly long (if this is the root cause). It always counts in minutes, this bad experience sometimes makes me depressed, and sometimes kills time unnoticeably. So do you have any suggestions? I think provides a global switch to turn off the typechecking would be great. #lang typed/racket/no-check #lang typed/racket/base/no-check these two #langs only affects there own file (also, there is no typed/racket/gui/no-check). Do we already have that global switch? Thanks. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.

I guess this make sense to me (partially). Probably the user has to have in mind how this works, since this could be source of confusion for some new users; like in the case of counting lines. If we use the two same files from the original example, using `wc' from the GNU coreutils, one would expect to get 3 lines and 2 lines respectively: wc -l data/file1.txt # => 3 data/file1.txt wc -l data/file2.txt # => 2 data/file2.txt on the other hand, if the user tries to count the number of lines based on the structure returned by `read-words/line' it would return 3 for both cases. (length (read-words/line "data/file1.txt")) ; => 3 (length (read-words/line "data/file2.txt")) ; => 3 Probably it would be a good idea to document this behavior so it doesn't surprises the new user. Also, one of the responses from Matthias caught my attention where he mentioned that he wasn't able to reproduce this on his Mac.

Hi WarGrey, (sorry for the delayed response) On 2016-04-09 14:39:31 +0800, WarGrey Gyoudmon Ju wrote: >So, is it safe to just ignore the non-paired value in instantiate.rkt? This error is coming up likely due to some bug in the Typed Racket contract generation code (which is what that instantiate.rkt module does). But if you don't get the error in your actual code, it likely means the contract is getting generated and is hopefully safe. If you can send me whatever code is necessary to reproduce the bug (even if it's not very minimal), I can try to fix it.
