Implement lambda calculus including an eta-conversion, fixed point combinators, ...<br />Good idea for course semester project.<br />See the wizard book for manifest types and Essentials of Programming Languages Friedman et al, not the last edition, the black cover, to implement lambda-calculusAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-11295132.post-90894412985340293942009-02-24T03:38:00.000-08:002009-02-24T03:38:00.000-08:00D'oh, ignore that last comment, I mistakenly thought it was returning a pointer to the structure not a copy. :-/Petehttp://www.blogger.com/profile/08075296498582938825noreply@blogger.comtag:blogger.com,1999:blog-11295132.post-23830574195674728712009-02-24T02:33:00.000-08:002009-02-24T02:33:00.000-08:00This code is dangerous and will likely crash since you are returning pointers to memory allocated on the stack!Petehttp://www.blogger.com/profile/08075296498582938825noreply@blogger.comtag:blogger.com,1999:blog-11295132.post-31142675923932543882007-09-17T19:10:00.000-07:002007-09-17T19:10:00.000-07:00Thanks for the nice post!Michaelhttp://free-ps3-for-me.blogspot.comnoreply@blogger.comtag:blogger.com,1999:blog-11295132.post-58841270328318413342007-03-02T06:27:00.000-08:002007-03-02T06:27:00.000-08:00Monads work in eager or lazy languages, it makes little difference. In a sense monads are just mathematical constructions defined by some equations, so what matters is what things evaluate to, not the order they're evaluated in.<BR/><BR/>Having said that...in Haskell there is a nice way to use monads to make it convenient to write strict code even though the language is lazy.sigfpehttp://www.blogger.com/profile/08096190433222340957noreply@blogger.comtag:blogger.com,1999:blog-11295132.post-28067538437690548132007-03-02T02:45:00.000-08:002007-03-02T02:45:00.000-08:00Well, all these C functions are eager. Isn't it the main point that Haskell functions are lazy? Or it doesn't really matter?Anonymousnoreply@blogger.com
