Learning Jai via Advent of Code

Has features similar to zig comptime. String macros and structured macros plus reflection and AST. Manual memory with fine-grained control of allocators, pointers. A few categories of interesting directives.

Semantic

  #complete          exhaustive enum check
  #must              return value must be used
  #specified         enum values must be explicit
  #symmetric         2-arg function can be called either way
  #type              next statement is a type

Optimize

  #asm               inline assembly
  #bake_arguments    bake argument into function
  #bytes             inline binary data
  #no_abc            disable array bounds checking
  #no_padding        specify no struct padding
  #place             specify struct member location

Meta

  #code              statement is code
  #compiler          interfaces with compiler internals
  #compile_time      compile-time true/false
  #expand            function is a macro
  #insert            inject code
  #intrinsic         function handled by compiler
  #placeholder       symbol will be generated at compile-time
  #procedure_name    acquire comp-time procedure name
  #run               execute at compile-time
  #type              next statement is a type

Clean syntax. Reasonable modules. A build system. No mention of package management though. Didn't cover "using" and data oriented programming much.

Overall looks like a reasonable competitor for systems or game programming.
