+# Remove `r_print!` and `r_println!` Macros
+
+`r_print!` and `r_println!` are important macros in Mingling for use inside `#[help]` and `#[renderer]` functions, but their implementation is not clean: they implicitly introduce a `__renderer_inner_result` field. While this might look elegant at the API level, it is **incorrect** and even **objectionable**.
+
+## Why **Objectionable**?
+
+Because you can't define declarative macros with `macro_rules` that wrap them.
+
+This is because `r_println!` depends on the implicit variable `__renderer_inner_result` injected by the `#[renderer]` proc macro into the function body. However, when a `macro_rules` declarative macro expands, **its internal code is placed in the caller's context**, which does not contain `__renderer_inner_result` — that variable only exists within the direct scope of the function body processed by `#[renderer]`.
+
+Let's look at some code to see why:
+
+```rust
+// Suppose you want to write a wrapper macro:
+macro_rules! my_println {
+    ($($arg:tt)*) => {
+        // When expanded here, the context is the call site of my_println!,
+        // not the location where the renderer function's injected variables live.
+        // So __renderer_inner_result is NOT visible here!
+        r_println!("Custom: {}", format!($($arg)*));
+    };
+}
+ 
+#[renderer]
+fn render_something(_p: ResultSomething) {
+    // Although this function body has __renderer_inner_result injected,
+    // the code from my_println! does NOT expand "inside this function body" —
+    // macro_rules expansion is essentially text replacement. The replaced code
+    // lives at the line where my_println! is called, and any variables referenced
+    // inside that macro must resolve to identifiers accessible at the call site.
+    // __renderer_inner_result is not a public, path-accessible variable;
+    // it's a hygienic local variable generated by the `#[renderer]` macro,
+    // and external macros cannot directly access it by name.
+    my_println!("{}", box_val); // Compile error: cannot find __renderer_inner_result
+}
+```
+ 
+## Deeper Issues
+
+I have to admit, this is an early design flaw. After re-examining the code, I found the problem goes beyond "can't be wrapped".
+
+This isn't just a "can't wrap" issue — it reflects that `r_println!`'s design fundamentally violates Rust's macro hygiene principles:
+
+- **Implicit dependency**: Users of the macro must know that a variable named `__renderer_inner_result` exists — but this variable is neither part of the public API nor explicitly documented anywhere.
+- **Scope leakage**: Variables injected by a proc macro should be confined to the scope processed by that macro. But `r_println!` attempts to make that variable accessible across macro calls, which effectively breaks Rust's identifier hygiene.
+- **Non-composable**: Any attempt to wrap `r_println!` will fail, because declarative macros cannot "pass through" access to implicit variables. Even using a proc macro to wrap it would encounter similar hygiene issues.
+
+## Desired New Syntax
+
+I've designed two alternative approaches and will choose based on actual needs.
+
+### Option 1: Explicit Return
+
+```rust
+#[renderer]
+fn render_something(prev: ResultSomething) -> RenderResult {
+    let mut result = RenderResult::new();
+    result.println(prev.to_string());
+    // or
+    write!(result, "{}", prev.to_string());
+ 
+    result // return here
+}
+```
+ 
+Clear boundaries — the entire rendering process is confined within the function body decorated by `#[help]` or `#[renderer]`, without introducing extra out-of-scope dependencies. The trade-off is slightly more boilerplate compared to the original approach.
+
+### Option 2: Resource Injection
+
+```rust
+#[renderer]
+fn render_something(prev: ResultSomething, result: &mut ResRenderResult) {
+    result.println(prev.to_string());
+    // or
+    write!(result, "{}", prev.to_string());
+ 
+    result // return here
+}
+```
+ 
+More flexible, but blurs the boundary between logic functions like `#[chain]` and rendering functions like `#[help]`.
+
+### Preferred Direction
+
+I lean toward **Option 1 (Explicit Return)**. There's no need to turn `RenderResult` into `ResRenderResult` as a global resource.
+
+As for rendering in logic functions like `#[chain]`, that should be handled by a separate system — not discussed here.
