Crystal Description
Crystal's syntax is heavily inspired from Ruby's. It feels natural to read, easy to write, with the added benefit that it requires less learning curve for Ruby devs. Crystal is statically type-checked so errors in type will be caught before they reach runtime. Crystal also has type inference built-in, which means that most type annotations are unnecessary. Crystal makes all types non-nilable. The available variables are represented by a union of the type and null. The compiler will check for null references during compile time. Crystal's solution to metaprogramming is a powerful macro-system that covers everything from types inspection and basic templating to types inspection and running arbitrary programs.

Cython
Cython, an optimizing static compiler, is available for both the Python programming languages and the extended Cython programming languages (based on Pyrex). It makes it as easy to write Python extensions using C. Cython combines the power of Python with C, allowing you to write Python code that calls back to C or C++ natively at any time. Static type declarations can be used to convert readable Python code into plain C performance. Combine source code level debugging to identify bugs in Python, Cython and C code. Large data sets can be interacted with efficiently, e.g. Multi-dimensional NumPy arrays. You can quickly build your applications in the mature, well-used CPython ecosystem. The Cython language, which is a superset Python language, supports calling C functions as well as declaring C types on variables or class attributes.

Scala
Scala combines object-oriented programming with functional programming in a single, concise language. Scala's static type system helps avoid bugs in complex applications. Its JavaScript and JVM runtimes allow you to build high-performance systems and have easy access to large libraries. Scala is intelligent about static types. You don't usually need to tell Scala what the types of your variables are. Instead, it will use its powerful type inference to figure them out. Scala uses case classes to represent structural data types. They implicitly equip the class using meaningful toString, equals, and hashCode methods. They also have the ability to be deconstructed using pattern matching. Scala functions are values. They can be described as anonymous functions using a concise syntax.

Zig
Zig is a general purpose programming language and toolchain that allows you to maintain robust, optimal, and reusable software.
Instead of worrying about your programming language knowledge, focus on debugging the application.
A new approach to metaprogramming that relies on compile-time execution and lazy evaluation
No hidden control flow.
There are no hidden memory allocations.
No preprocessor, no macros.
Any function can be called at compile-time
You can manipulate types as values with no runtime overhead.
Comptime imitates the target architecture.
Zig is a zero-dependency drop-in C/C++ compiler, which supports cross-compilation right out-of the box.
Use zig build to ensure consistency across platforms.
You can add a Zig compilation unit into C/C++ projects. Cross-language LTO is automatically enabled.

Component Pascal
Component Pascal is a general purpose language in the tradition Oberon, Modula-2 and Pascal. It has the following key features: block structure, modularity and static typing with strong type-checking (also across module boundaries), type extension using methods, dynamic loading modules and garbage collection. Component Pascal is an object-oriented language because it supports type extension. An object is a variable in an abstract data type that contains private data (its state), and the procedures that operate on it. Extensible records are used to declare abstract data types. Component Pascal covers the majority of terms in object-oriented languages using the established vocabulary for imperative languages to reduce the number of notions related concepts. Component Pascal is a component-oriented language. It has complete type safety and requires a dynamic object model.
