* [Caml-list] keeping parameter polymorphic @ 2012-10-04 13:03 rixed 2012-10-04 13:13 ` Gabriel Scherer 0 siblings, 1 reply; 2+ messages in thread From: rixed @ 2012-10-04 13:03 UTC (permalink / raw) To: caml-list Hello. I can't find a way to keep f polymorphic in: let test f = f 1, f true that I'd like to return a int*bool from any function 'a->'a I now this question regularly pops up, but I've tried many combinations of "(type a)" and "'a." to no avail (ocaml 3.12.1 here). (in real world, my function takes a generic "fold" function that I'd like to use with various types). ^ permalink raw reply [flat|nested] 2+ messages in thread
