I feel like inheritance is the actual problem with OOP. Trees of types with increasing specialisations just don't describe many real world problems that well. When you do build programs like this, code gets more and more rigid until it

My comment history is 90% talking about Nim because this is the account I talk about Nim on :) Probably it's the same for other people. My last comment was 7 months ago on the 1.0 release. It seems like when talking about a smaller lan

You're right no dependent types, though to be fair that wasn't the only thing mentioned, and none of the other replies have yet suggested a language with dependent types either. I was responding to: > ...great tooling and moder

Have a look at Nim: https://nim-lang.org/ It's a system language that's focused on readability and performance. It has OOP but isn't focused on it, and has some of the best AST metaprogamming out there built

In hindsight maybe the "performers" table would be better named "resultVars", as that's what it really represents.

Metaprogramming is one of the core ideals in the birth of the language so is well supported. Personally I've not used Lisp, so can't comment there, but it is on the list of influences on the homepage. Essentially there's a VM

I wouldn't say separating the GC at the type level is a major innovation, but as you say it's useful. I don't think Nim really sells itself on a groundbreaking GC implementation either. However it does give you a fast GC with

Basically you only use GC if you declare something using a GC type. type # A `ref` type is GC and will use the heap. MyGCType = ref object fieldA: int # Otherwise ALL types are stack based. MyStackType = object

This is a bit like saying you wouldn't use LLVM languages because of the semantics of IR, or that you have to understand the guarantees IR provides, isn't it? Ultimately if you're really interested in performance, regardless

I would say metaprogramming (and maybe the excellent FFI) is the huge stand-out feature for Nim. However whilst you can compare all these languages and find a particular niche or set of features that sell them, Nim is just good at pretty mu

Well the Nim team at Status is a separate team working on an open source Ethereum 2.0 implementation, rather than any blockchain 'product' (unless you count a working 2.0 client as a product). Their goal is to get Eth2.0 (and 1.0)

Mundane typing? Typing is awesome! Haven't you ever wondered what a parameter actually is in say, Python, and have to track back through callers to work out what the parameter is expected to contain? Completely solved by specifying typ

Definitely fits the bill: * Python-like syntax * Compiles to C/C++/JS/Object-C * Supports Windows, Linux and Mac. * Multithreading * Extensive metaprogramming * VERY fast compiler * Dead code elimination * Very strongly typed

Nim ameliorates this somewhat by being able to easily wrap any C/C++ libray, and even has c2nim to create wrappers automatically. One of the advantages of compiling to C and C++.

However Delphi has more modern language features than Go, such as generics, full object orientation and reflection.

A bit hyperbolic, there are loads of languages that are case insensitive. Are you really only using case to distinguish different variables? That seems more error prone.

To be fair, this is library FFI code so this is actually for interfacing with C++ rather than 'native' Nim. Probably not something you'd encounter unless you're making a library wrapper. And if you are doing that, worth
