Availability

• Compiled (AOT): supported by the Elephc code generator.
• eval() (magician interpreter): supported through a declarative interpreter builtin (crates/elephc-magician/src/interpreter/builtins/raw_memory/buffer_ptr.rs).
• Strict PHP mode: hidden - this builtin is an elephc extension with no PHP equivalent, so programs compiled with --strict-php treat the name as nonexistent, in compiled code and inside eval’d code.

No examples yet. Check examples/ and showcases/ for usage patterns.
