Re: Strange exception: Cannot cast to compile stub??

If I recall correctly, looking at the code at around line 483, I think I have seen that error arise when using (set! (.fieldName this-reference) value) inside defrecord and deftype bodies. if you use (set! fieldName value) syntax you might be fine. On 05/08/2016 07:21 PM, JvJ wrote: > I'm implemen

Serialising/deserialising mixed Clojure and Java datastructures

I'm working on some complex analysis where it takes about twelve hours to construct the model to be analysed. Once it's constructed I'm doing various interactive things to explore it, but I can't currently persist it in a form in which it can be read back in, so that when the REPL session ends i

Re: Serialising/deserialising mixed Clojure and Java datastructures

Clojure is designed with enough extensibility to modify the printer and reader to cover this case. You can define a custom print strategy for these types by extending the print-dup multimethod. If you print it as a tagged literal, you can also define a custom reader that can read it back as the

Re: Strange exception: Cannot cast to compile stub??

Changing the set! syntax fixed the issue. Thanks! There's no way I could have figured that out on my own. On Monday, 9 May 2016 01:12:36 UTC-7, red...@gmail.com wrote: > > There is a jira issue http://dev.clojure.org/jira/browse/CLJ-1226 and it > looks like it is marked as fixed in 1.8 > > On

Addressing Matthias Felleisen's concerns?

At Clojurewest 2016, Matthias Felleisen gave a great keynote about the pragmatism of soundness for maintening large code bases. He mentioned that adding type gradually was useful, but only when the border between typed land and untyped land is guarded. He mentioned how Racket does that. He also

Re: Transducers improve performance more than expected

In a similar vein, do you think that eductions are generally a better idea than lazy sequences/for comprehensions? On Sunday, 8 May 2016 22:24:15 UTC-7, Herwig Hochleitner wrote: > > My theory has been, that transducer stacks inline much better, hence allow > for more optimizations by the jit. >

Re: Addressing Matthias Felleisen's concerns?

(Did he mention Wadler? Probably. http://lambda-the-ultimate.org/node/2538) I have it from friends who have used TR "in anger" that it is not really a win. My own experience with other things, e.g. the typed stuff in the lands of JavaScript and TypedLua, is in line with that, unfortunately. http:/

Josh is correct. I'm currently working on merging this work now that my courses are over. Thanks, Ambrose On Mon, May 9, 2016 at 6:32 PM, Josh Tilles wrote: > On Monday, May 9, 2016 at 5:36:53 PM UTC-4, Didier wrote: >> >> At Clojurewest 2016, Matthias Felleisen gave a great keynote about the >

Re: Transducers improve performance more than expected

eductions are non-caching (will re-perform their work each time they are used), so most of the time I would say lazy sequences are preferable. On Monday, May 9, 2016 at 4:54:48 PM UTC-5, JvJ wrote: > > In a similar vein, do you think that eductions are generally a better idea > than lazy sequenc
