The Perlang Programming Language

About

Perlang is a general-purpose programming language which aims to incorporate the following concepts (or paradigms if you so prefer):

  • static typing
  • strong type inference
  • immutability by default, mutability where required
  • safe by default, unsafe where required
  • object-orientation
  • functional programming

Perlang deliberately aims to be a low-barrier language, much like scripting languages like Ruby, JavaScript and Python. As soon as you have the perlang binary available, you can start writing your program. Much like these other languages, there is a minimum of "ceremony" required: you don't have to declare a top-level class (or even function!). You can focus on the essentials of "getting things done" and start hacking right away.

At the same time, these concepts (functions, classes1, type-parametric polymorphism2 etc) are there, readily available in the "toolbox" whenever your program grows to the point where you need it. No need to rewrite your program in some other, "better" (or more performant) language as its needs evolve. Perlang aims to have both of these use cases covered.

Similarly, we refuse to prematurely force the user to decide whether to use one of the following:

  • a "scripting-based" ("rapid prototyping") language, with a great "edit-run" cycle, often at the cost of inferior performance and a weaker (dynamically typed) type system
  • a "general-purpose object-oriented language" like Java, C# or Go (which tries to strike a balance in most tradeoffs between e.g. performance and programmer productivity)
  • a "system programming language" like Rust, C or C++, with great performance and features necessary for proper "bare-metal" support

Often you know what kind of program you are writing when you start out, but really, why should you be forced to learn at least three different languages (one scripting-based, one general-purpose and one system programming language) for this? Wouldn't it be much better if we could make a language that can excel in all of these domains?

Perlang aims to be just that. Welcome to join our journey.
