1. *Recursive Hook Guard*
One of the biggest pitfalls in hooking is "recursion death." If you hook malloc and your hook (or a
library it uses, like println!) calls malloc, the program will crash with a stack overflow.
 * Suggestion: Provide a thread-local guard utility or a macro attribute like #[hook(guard = true)]
   that automatically skips the hook logic if it's already being executed on the current thread.

2. *Relative Symbol Offsets*
Currently, users have to choose between a symbol (start of function) or a raw offset (from binary
base).
 * Suggestion: Allow offsets relative to a symbol. For example: #[hook(symbol = "complex_logic", offset
   = 0x42)]. This is much more resilient to binary updates than an offset from the base, as only the
   specific function needs to be re-analyzed if the binary layout changes.


3. *Type-Safe Register Helpers*
The Registers struct is currently a raw collection of usize. 
 * Suggestion: Add helper methods to the Registers struct (or a wrapper) to make argument extraction
   more intuitive, especially for Jmp hooks where the proc-macro doesn't automatically extract args.
 * Example: let val: i32 = reg.arg(0); or reg.set_arg(1, 100);.

4. *Multi-Arch Foundations*
While you are currently targeting x64 Linux, the logic is very close to being portable.
 * Suggestion: Abstract the register extraction logic behind a trait. This would allow you to support
   arm64 (common on Mac/Android) or x86 later without rewriting the proc-macro logic, just by swapping
   the register-mapping module.

5. *Hook "State" (Context)*
Currently, if a hook needs to maintain state (like a counter), it must use a global Mutex or Atomic.
 * Suggestion: Allow the HookRegistry to pass a user_data: usize (which ilhook supports) into the hook
   function. This would allow users to associate specific data with a hook instance at runtime without
   relying on global statics.
