THINGS ZIG COMPTIME WON'T DO

Summary from the TLDR Web Dev newsletter

While many languages support generics, serialization, and metaprogramming at compile time, Zig enforces strict boundaries: no access to the host machine during cross-compilation, no dynamic code generation (#eval-style mixins), no custom syntax or DSLs, and no runtime type info (RTTI). Instead, Zig has partial evaluation and specialization, allowing for expressive and safe compile-time behavior.
