Let's analyze the handler type and the overall design, and then suggest improvements.

Current Design Analysis

handlers: RefCell<HashMap<String, Box<dyn Fn(Vec<Box<dyn Any>>)>>>: This is the core of the question. It stores event handlers.

String: Event name (key). Seems reasonable.

Box<dyn Fn(Vec<Box<dyn Any>>)>: The handler itself. This is the part we'll scrutinize. It takes a Vec<Box<dyn Any>> as input.

144 x 443 x 993 x 223

Okay, so I need to multiply these four numbers: 144, 443, 993, and 223. Hmm, that seems like a lot. Let me think about how to approach this step by step. I know that multiplying all of them at once might be complicated, so maybe breaking it down into smaller parts would be better. Let me start by multiplying the first two numbers, 144 and 443, and then multiply the result by 993, and finally multiply that by 223. But before jumping into calculations, maybe I can check if there's a smarter way to simplify this, like looking for factors that can make the multiplication easier.

First, let me write down the numbers: 144 × 443 × 993 × 223. Let me see if any of these numbers can be broken down into smaller factors that might pair nicely with others. For instance, 144 is 12 squared, which is 12 × 12. 443... Hmm, is that a prime number? Let me check. 443 divided by 2 is not an integer, 443 divided by 3 is 147.666..., so not divisible by 3. The square root of 443 is about 21, so I need to check
