C3 programming language

“C3 lang gives you defer + a lot of significant ergonomic improvements right now”

“It's my favorite of the new round of languages by far.”

“C3 is honestly so good and a bit underrated.”

“The C3 temp allocator leans into this though. It's not a frame allocator but acts like a stack allocator.”

“I stumbled upon the language earlier this year and love it.”

“everything about C3 is super exciting”

“it adds a few useful things to libraries and to generic compile time introspection”

“C3 just has everything C compatible so not just calling into C but also C calling to C3 is just completely normal”

“Some people just prefer alternatives, be it C, C3, Odin, Zig, Jai or whatever else there is.”

“C3 even named these types differently, so they're certainly under no obligation to provide the wrapping unsigned integers”

“like V (when it came into existence), Zen C (4K stars since 2025) had a sudden burst in stars. Allowing it to nearly catch a long time repo like C3”

“In the case of C3, breaking changes only happen once a year with stdlib going through the general process of deprecating functions long before removing them.”

“breaking changes only happen once a year with stdlib going through the general process of deprecating functions”

“I really like the decisions made in C3”

“But the array indices being reversed on declaration? I cannot think of an upside to that at all.”

“these can be misinterpreted as a safety feature, while they actually add more possibilities for UB”

“swapping common terminology like that is a blunder from my perspective”

“The improvement is you just write 'type?' for the return type to enable this and you don't need an out param”

“I'll take order-independent declarations and fast modules over strictly sticking to C syntax any day.”

“It fits nicely because it allows better compilers to use the constraints to optimize more confidently”

“However, just like for const the compiler might not detect whether the annotation is correct or not!”

“It doesn't really add anything because 'void main()' already communicates it's a function.”

“I think that makes a lot of sense and fits perfectly with their “evolution, not revolution” philosophy.”

“C3 feels like home for C developers, there is a real market for language evolutions rather than revolutions”

“But it's unexpected for a language that bills itself as "The Ergonomic, Safe and Familiar Evolution of C".”

“I like the idea of strict improvements to C without taking anything away”

“choosing a conflicting name for an extremely common abstract data type”

“I find it more fun to program in compared to plain C, and it's definitely more simple than reaching for C++.”

“leaving out move semantics and destructors is inexcusable at this point”

“sad to see that there is nothing special for matching or restructuring tagged unions”

“designed around supporting separate compilation and dynamic linking”

“Specifying those assumptions in the code, instead of in flags to the compiler, seems like a win.”

“sometimes instead of catching a mistake, these checks will instead silently introduce undefined behaviour into your program”

“the first thing I noticed in their example is a double-colon scope operator”

“it adds a few very desirable things, such as introspection and macros”

“C3 provides a module system for cleaner code organization across files”

“the idea of ABI compatibility with C is pretty ingenious”

“I think the switch statement design is a foot gun: defaults to fall-through when empty and break when there is a body.”

“The killer feature for me is the full ABI compatibility.”

“This is what a website for a programming language should look like.”
