After watching the interview with Rich Hickey on Protocols in Clojure 1.2, and knowing very little开发者_如何转开发 about Clojure, I have some questions on Clojure Protocols:
I needed some recursive structural type in some piece of code using with traits and the structural type as type parameter constraint. It worked fine, but later I learned Scala does not support recursi
I was reading (ok, skimming) Dubochet and Odersky\'s Compiling Structural Types on the JVM and was confused by the following claim:
I\'m interested in the problem of conforming a specific type to a more general structural type.Consider the following examples:
I\'m trying to write a generic interpolate method that works on any type that has two methods, a * and a +, like this:
In C++ how to tell compiler that Ogre::Vector3 IS_SAME_AS SomeOtherLIB::Vector3 ? I feel that.. in languages like c++ which are not structural typed but th开发者_Go百科ere are cases when it makes sens
I\'m trying to define a structural type defining any collection that has an \"add\" method (for instance, a java collection). Using this, I want to define a few higher order functions that operate on
Let\'s have a following example: public class X { } public class Y { } public class Z { } public delegate IDictionary<Y, IList<Z>> Bar(IList<X> x, int i);
