    There's not much information on it, but the crystal-lang people also ran into an issue that looks similar, as the language uses M:N threading
  • Downsides (andUpsides) of ruby ? / tips for novice (w/Python) ? | 2021-09-11
    Here's where things get a little confusing. There are now languages which have the same syntax as Ruby or Python, but are compiled languages. Crystal has the same syntax as Ruby, but with a compiler that compiles down to native object code and optional Strong Typing (it's like Static Typing, but without the implicit type conversion). Nim has the syntax of Python, but with a compiler that can compile down to native object code and Static Typing. This means that when you need the performance and Type System of a compiled language (ex: performance is a key requirement, or you need to replace slow code in your project with faster code), you don't have to learn a completely different language from Ruby or Python. You can easily switch between Ruby and Crystal, or Python or Nim, and get the best of both worlds.
  • Types as a Learning Tool with Crystal and Lucky | 2021-09-03
    Years ago, I had looked a little bit at Crystal, but I was afraid that taking Ruby and adding types would end up feeling clunky. Upon digging in a bit more, it seemed a lot smarter than that and looks to have some incredible performance possibilities. After discovering that there was also a well-documented and interesting looking web framework called Lucky, I was ready to give it a shot.
  • How does Ruby feel for someone with a staticaly typed background (Scala) | 2021-08-31
    Coming from C, C++, Java, I found Ruby classes to be a lot like Java classes but without the additional formality. The OOP paradigm is still there (everything is an object in Ruby), but there's no abstract keyword or interfaces or virtual friend methods (although there's modules and protected methods). Ruby is duck-typed, so a lot of the time you just have to trust that the right type of data is given to you (although you can still do explicit type checking with obj.kind_of?(Foo) and raise an ArgumentError or TypeError). In order to remember what types a method should receive, I document them using YARDoc (similar to JavaDoc but for Ruby). If you want Ruby syntax/stdlib and a more traditional Static Typed experience, checkout Crystal which provides both Type Inference and Strong Typing.
  • How do I create a ruby application? | 2021-08-24
    Depending on what you're doing, that might be good enough for you. If not, you may want to consider using a compiled language. Crystal ( is a compiled language based on ruby that might work well for you, though it is still in its infant stages in terms of third party libraries.
  • It's perfectly possible to write a statically-typed language that looks exactly like Python or Perl or Ruby. It's just that nobody's done it yet. (2011)
  • Do you think Crystal has a future in the Ruby community? | 2021-08-17
    Recently I learned Crystal and is really cool project. Is amazing to see how good ruby syntax and static typing working together in compiled type language.
