Why people recommend it

Each mark is one comment

  • Strong compile-time metaprogramming and reflection

    “For one in D it's the same language and one can choose whether to execute compile time constant parts at compile time”

    Comment from 12 Feb 2026 in “D Programming Language”

    “Languages such as D and Nim (both greatly underappreciated) offer full-language compile-time interpretation.”

    Comment from 8 Nov 2025 in “Why is Zig so cool?”

    “D has compile time reflection, and compile time metaprogramming is much easier to use than Rust macros”

    Comment from 12 Feb 2026 in “D Programming Language”
  • Consistent, well-designed syntax and type system

    “It's a very consistent language even if you compared to the other popular languages namely Python, Rust, C++ and Go.”

    Comment from 12 May 2026 in “If AI Writes Your Code, Why Use Python?”

    “It has a type system that catches most category errors, without having to think too much about types”

    Comment from 28 Jul 2026 in “DConf 2026 in London”

    “I like how easy it is to switch between low-level and high-level code, and it has some neat features for modeling data.”

    Comment from 18 Oct 2026 in “Show HN: Parin – A 2D game engine between raylib and Godot, written in Dlang”
  • Easy C interop and porting

    “After using a mixed D/C program for a while, I bet you'll feel motivated to take the extra step and translate the C stuff to D”

    Comment from 24 Jan 2026 in “Some C habits I employ for the modern day”

    “it's almost a no-brainer to port C/C++ code to D because it mostly builds on the same semantics”

    Comment from 12 Feb 2026 in “D Programming Language”

    “In D, you just import the C headers directly without depending on the bindings' maintainers.”

    Comment from 12 Feb 2026 in “D Programming Language”
  • Garbage collector plus systems control

    “D language pioneered this combination both GC (by default) and non-GC more seamlessly, even before Stanza.”

    Comment from 4 Jun 2026 in “Elixir v1.20 released: now a gradually typed language”

    “the GC combined with the full power of a systems language are the killer features that made me stick to D”

What people warn about

Each mark is one comment

  • Unstable, confusing ecosystem

    “the whole ecosystem was just too confusing and simply didn't look stable and reliable enough to build upon long-term”

    Comment from 12 Feb 2026 in “D Programming Language”

    “D to me is one language I love fundamentally, but the ecosystem is nowhere near where it could be.”

    Comment from 10 Jul 2026 in “Interview with Mitchell Hashimoto about Ghostty and Zig”

    “There's just too many problems with this language and how it's packaged and offered to the end user”

    Comment from 12 Feb 2026 in “D Programming Language”
  • No clear direction, too many features

    “lack of direction (it is always trying the next big thing that might atract users, leaving others behind not fully done)”

    Comment from 2 Feb 2026 in “Data Processing Benchmark Featuring Rust, Go, Swift, Zig, Julia etc.”

    “D is mostly a collection of many ideas, many of them are good, but they don't coalesce into a simple design philosophy”

    Comment from 20 Sep 2026 in “What Zig felt like, coming from Rust”

    “D has become a complicated kitchen-sink language where each concept seems to be implemented in three different ways”

    Comment from 1 Jul 2026 in “Zig – SPIR-V Backend Progress”
  • Weak IDE and tooling support

    “With all your tools you're never going to reach the same level of interactive productivity with D”

    Comment from 25 Mar 2026 in “Data Manipulation in Clojure Compared to R and Python”

    Comment from 28 Jul 2026 in “DConf 2026 in London”
  • Lost years and delayed releases

    “D has lost 16 years counting from Andrei's book publishing date, letting other programing languages catch up to more relevant features.”

    Comment from 13 Feb 2026 in “D Programming Language”

    “was for several releases delayed due to personal issues, which is understandable in a small team, however it is a problem.”
