Universal Function Call Syntax (UFCS) in D Language
One of the many “cool’ features of Dlang is “Universal Funcion Call Syntax”, which permits non-member functions to be invoked using the member function…
Calling Lisp Functions from D Language
After exploring “newLisp” in the past few posts, I would like to start looking at the “D Programming Language” (DLang). DLang has been around since 2001.…
The “net-eval” Function in “newLisp”
One of the cool things about “newLisp” is that despite its small fooprint, it comes with a lot of functionality built-in. For instance, if you…
Understanding the “unify” Function in “newLisp”
Unification between two symbolic expressions involves finding substitutions for variables (if any) in the expressions such that the expressions match after applying the substitutions. This…
Currying in “newLisp”
In the last two articles, I discussed what I believe are some interesting features of “newLisp”. Today’s topic is “currying”, another useful feature. For…
Implicit Indexing and Slicing in “newLisp”
In traditional Lisp (Common Lisp), when evaluating an S-expression list, the first element in the “functor” position must be a function or valid operator.…
Some Interesting Features of “newLisp”
newLisp is a general-purpose scripting language with a Lisp-like syntax. That is one of the reasons I wanted to take a closer look at…
Using Sicstus Prolog with LMDB
In an earlier article, I showed how Sicstus Prolog allows us to use Berkeley DB for storage and retrieval of terms using the file…
C++ 20: Concepts
Concepts, introduced in C++20, are predicates that act as contraints on template parameters. As you would expect, the nice thing is that the constraint…
Ring Language: Dynamic Behavior of Classes and Objects
We have been exploring the Ring Programming Language in the last two articles. Ring is a dynamic programming language with many interesting features. In today’s article,…
