MLton features and specs

  • Performance
    MLton is known for producing highly optimized, efficient executables due to its whole-program compilation approach. This can result in faster performance compared to other Standard ML compilers.
  • Standard ML Compliance
    MLton has strong adherence to the Standard ML language specification, ensuring that programs written for MLton are highly portable and conform to the expected language standards.
  • Rich Optimization
    The compiler includes numerous optimization techniques, enabling better runtime performance and memory usage for compiled applications.
  • Large Language Support
    MLton supports the full breadth of the Standard ML language, including advanced features like functors and modules.

Possible disadvantages of MLton

  • Compilation Time
    Due to its whole-program optimization techniques, MLton can take longer to compile programs compared to other compilers that use separate compilation.
  • Executable Size
    Although MLton optimizes for performance, this can sometimes result in larger executable sizes than compilers that don't perform as many optimizations.
  • Limited Interactivity
    MLton is optimized for batch processing and does not provide interactive development features like a REPL (Read-Eval-Print Loop), which can be a downside for some developers used to interactive programming environments.
  • Platform Availability
    While MLton supports several platforms, its availability may not be as widespread as other more commonly used programming environments, which could limit use in certain contexts.

Possible disadvantages of CodeSignal

  • Cost
    The platform can be expensive for small and medium-sized businesses, limiting its accessibility to larger organizations with bigger budgets.
  • Learning Curve
    Though user-friendly, there may be a learning curve for new users, especially those not familiar with technical hiring tools.
  • Limited Candidate Pool
    Since users need to have some level of coding proficiency to perform well, it might not be suitable for assessing candidates who are just starting out or are from non-technical backgrounds.
  • Potential for Overfitting
    Candidates familiar with CodeSignal's specific types of questions and problems may perform better, which might not always reflect their overall coding abilities.
  • Internet Dependency
    As a cloud-based platform, it requires a stable internet connection, which might pose challenges in regions with limited connectivity.

  • Simple JSON parser in c++, rust, ocaml, standard ml
    Once I got the parser ready in OCaml, I thought I port it to Standard ML, since it belong to the same ML language family. I was also curious on how well mlton could optimise it. The language lacks custom let bindings, so I resorted to use Result.bind manually. This makes code much less readable and more verbose. The standard library also lacks result type, so I had to come up with my own simple implementation.... - Source: dev.to / over 2 years ago
  • Ante: A low-level functional language
    If you’re fine with tracing GC (which depends on the situation, of course), Standard ML is a perfectly boring language (that IIUC predated and inspired Caml) and MLton[1] is a very nice optimizing compiler for it. The language is awkward at times (in particular, the separate sublanguage of modules can be downright unwieldy), and the library has some of the usual blind spots such as nonexistent Unicode support... - Source: Hacker News / almost 3 years ago
  • Write your own programming language in an hour with Chumsky
    Unfortunately, I haven't found a ton of "easily-digestible" and, at the same time, comprehensive guides on compiling functional languages. Generally you'll find a mix of blog posts/class notes/papers covering a single step. Some resources I like: - Andrew Kennedy's 2007 paper Compiling with Continuations, Continued [1]. This one is the most clear IMO - Andrew Appel's Compiling with Continuations book... - Source: Hacker News / about 3 years ago
  • Why are imperative programs considered faster than their functional counterparts?
    More broadly, they can be fast even without such extensions if they aggressively pursue optimization opportunities afforded by static typing, like MLton for example, but that also impacts compilation performance negatively. Source: over 3 years ago
