search for: multimethods

I'm working on implementing a simple functional language in LLVM. It's statically typed, but I'd like to a have some simple multimethods involved. Does LLVM have some intrinsics for handling something like C++ vtables? Or do I need to implement my own way of handling single-dispatch functions? Thanks, Timothy -- “One of the main causes of the fall of the Roman Empire was that–lacking zero–they had no way to indicate successful t...

I thought this would be of interest to LLVM developers: The Fortress project, which was an attempt to create a very advanced language with implicit parallelism, parametric polymorphic types and many other cutting edge language features, has announced that they are winding down the project. What I found very interesting was that one of the reasons they gave was the lack of a suitable execution

One sort of questions why a company the size of Oracle, working with DARPA funding, wouldn't have the resources to design the virtual machine they required for the project... although reading the article they never do *quite* say that Fortress is being put down... just that the research group is winding down on it, the JVM target work isn't going to be completed, and the current

I created a subversion repository on my new vps and i''m trying to setup my rails app there. However i keep getting this error: subversion/libsvn_subr/io.c:2516: (apr_err=13) svn: Can''t create directory ''/home/svnadmin/rapleaf/db/transactions/0-1.txn'': Permission denied How do i fix this? I know others have had this before, so i would appreciate some help.

I started with Ruby on Rails in the 0.13.x period, so I''m sure I missed out on a lot of history. There''s probably some good explanation for something I''ve been wondering about, but I haven''t seen it written down anywhere. Maybe someone can clue me in. I''ve always felt that one of the uglier APIs was the ActiveRecord::find() method. I call

Dear R users, I am trying to simulate some multitrait-multimethod models using the packages sem and psych but whatever I do to deal with models which do not converge I always get stuck and get error messages such as these: "Error in summary.sem(M1) : coefficient covariances cannot be computed" "Error in solve.default(res$hessian) : System ist f?r den Rechner singul?r: reziproke
