+    The `emitc.member_call_opaque` operation represents a C++ member function
+    call. It takes a receiver operand, a callee string attribute (the method
+    name), and variadic operands for arguments.
+
+    The call allows specifying order of operands and attributes in the call as
+    follows:
+    - integer value of index type refers to an argument operand;
+    - attribute which will get lowered to constant value in call;
+
+    Example:
+
+    ```mlir
+    %0 = emitc.member_call_opaque %receiver "method" (%arg0, %arg1) : !emitc.opaque<"MyClass">, (i32, i32) -> i32
+    ```

+    StrAttr:$callee,
+    OptionalAttr<ArrayAttr>:$args,
+    OptionalAttr<ArrayAttr>:$template_args,
+    Variadic<EmitCType>:$args_operands
